Resonant electron-lattice cooling in graphene

Jian Feng Kong, Leonid Levitov, Dorri Halbertal, and Eli Zeldov

Phys. Rev. B 97, 245416 (2018) - Published 19 June, 2018

Novel ways to manipulate electron-lattice cooling in solids are of wide interest for both fundamental and applied research. This article describes a mechanism of tunable electron-lattice cooling mediated by defects in a graphene lattice, representing resonant scatterers with energy levels close to the Dirac point. The defects produce a resonant enhancement of cooling, which is analogous to the well-known Purcell effect in optics. Namely, the emission rate of phonons is greatly enhanced when the electronic Fermi energy is tuned to match the defect resonance energy. The ability to control both the cooling rate through electronic gating and the spatial location of cooling through precise defect engineering opens a route to designing cooling pathways in nanodevices.

Higher-dimensional Sachdev-Ye-Kitaev non-Fermi liquids at Lifshitz transitions

Arijit Haldar, Sumilan Banerjee, and Vijay B. Shenoy

Phys. Rev. B 97, 241106(R) (2018) - Published 14 June, 2018

Some of the most interesting phenomena in condensed matter occur in high-temperature superconductors and heavy fermions, and arise from a parent non-Fermi-liquid background. Although the non-Fermi-liquid phase has metallic character, it is very different from typical metals in that the electronic excitations are not particlelike (no quasiparticles), and this has lead to these phases eluding a clear theoretical description. Here, the authors develop a model that provides a route to describe non-Fermi liquids realized in condensed matter systems. Building on the zero-dimensional Sachdev-Ye-Kitaev model that is inspired by connections between a non-Fermi liquid and black holes, the authors construct a model in a lattice system where the bands touch to give a divergent density of states (Lifshitz point). The resulting non-Fermi-liquid phases exhibit intriguing properties such as scaling symmetry, nontrivial power-law dependence of entropy on temperature, and fast information scrambling with rate linear in temperature, as well as dynamical transitions to more conventional phases with well-defined quasiparticles.

Attractive Coulomb interactions in a triple quantum dot

Changki Hong, Gwangsu Yoo, Jinhong Park, Min-Kyun Cho, Yunchul Chung, H.-S. Sim, Dohun Kim, Hyungkook Choi, Vladimir Umansky, and Diana Mahalu

Phys. Rev. B 97, 241115(R) (2018) - Published 22 June, 2018

This work demonstrates that electron pairing can be achieved purely by the Coulomb interactions in a triple quantum dot. Such a pairing mechanism is different from that of a Cooper pair. The electron pairing in two dots of the triple dot is mediated by the other (third) dot, when the third dot strongly couples with the two via Coulomb repulsion. By measuring electron conductance through each individual dot, the authors find the degeneracy for the pairing, the condition for the degeneracy, and nontrivial transport behavior by the pairing. These findings may be exploited to design quantum devices with nontrivial electron correlations and functionalities.

Ramsey fringes in a room-temperature quantum-dot semiconductor optical amplifier

I. Khanonkin, A. K. Mishra, O. Karni, S. Banyoudeh, F. Schnabel, V. Sichkovskyi, V. Mikhelashvili, J. P. Reithmaier, and G. Eisenstein

Phys. Rev. B 97, 241117(R) (2018) - Published 26 June, 2018

Ramsey interference that enables careful control over quantum states is demonstrated here in an inhomogeneously broadened ensemble of quantum dots, which serve as the gain medium of a semiconductor waveguide operating at room temperature. A subfemtosecond-resolution pump-probe scheme reveals a clear oscillatory behavior of the amplitude and instantaneous frequency of the probe pulse. A unique phenomenon is also observed, whereby the temporal position of the output probe pulse also oscillates with the same periodicity. The latter cannot be observed in single-dot systems since it results from the distributed nature of the amplifier.

Valley switch in a graphene superlattice due to pseudo-Andreev reflection

C. W. J. Beenakker, N. V. Gnezdilov, E. Dresselhaus, V. P. Ostroukh, Y. Herasymenko, İ. Adagideli, and J. Tworzydło

Phys. Rev. B 97, 241403(R) (2018) - Published 5 June, 2018

In valleytronics, one seeks to employ the valley index of Dirac electrons in graphene as a carrier of information. This work shows that reflection from a superlattice potential can provide a valley switch: electrons in valley K approaching the superlattice near normal incidence are reflected into valley K′. The authors identify the topological origin of this effect, by mapping onto Andreev reflection from a topological superconductor. The valley switch is ideal at a symmetry point of the superlattice potential, yet remains close to 100% over a broad parameter range.

Observation of interlayer excitons in MoSe2 single crystals

Jason Horng, Tineke Stroucken, Long Zhang, Eunice Y. Paik, Hui Deng, and Stephan W. Koch

Phys. Rev. B 97, 241404(R) (2018) - Published 7 June, 2018

So far, spatially indirect or charge transfer excitons are only known to exist in certain heterostructures. Here, via confocal reflection spectroscopy and quantitative comparison with theoretical analysis using the Dirac-Bloch equations, the authors identify a previously unknown species of spatially indirect exciton in bilayer to multilayer MoSe2 single crystals. They coexist with spatially direct ones at a lower energy, stable only because of the two-dimensional nature of electrons in layered materials. The interlayer exciton binding energy and oscillator strength are comparatively large, enabling convenient optical access to dipolar systems and potentially powerful cavity effects.

Infinite family of three-dimensional Floquet topological paramagnets

Andrew C. Potter, Ashvin Vishwanath, and Lukasz Fidkowski

Phys. Rev. B 97, 245106 (2018) - Published 6 June, 2018

In thermal equilibrium, the interplay of symmetry and topology leads to a handful of topological insulating phases of matter with robust properties governed by topological invariants. This work investigates the nonequilibrium dynamics of three-dimensional systems of bosons, spins, or qubits, subject to time-periodic driving, and theoretically discovers an infinite family of new dynamical topological insulating phases that would not be possible in thermal equilibrium settings. These phases, called “Floquet topological paramagnets”, display anomalous surface dynamics, including magnetic domain walls that transport unidirectionally precisely quantized packets of quantum information per driving period, and new types of dynamically enriched topological orders.

Onset of Floquet thermalization

Asmi Haldar, Roderich Moessner, and Arnab Das

Phys. Rev. B 97, 245122 (2018) - Published 13 June, 2018

Interacting many-body quantum systems are believed to heat up unboundedly under a periodic drive as there is no local conservation law to prevent this from happening. Here, the authors show that this belief may not be generally true. Their results indicate that under strong periodic driving quantum interference may suppress the heating and may lead to a nonthermal state, remembering properties of the initial state until infinite time. This is accounted for by the emergence of an approximately conserved local quantity. The freezing is more pronounced for smaller drive frequencies, putting it beyond the scope of conventionally used high-frequency expansions.

Truncating the memory time in nonequilibrium dynamical mean field theory calculations

Michael Schüler, Martin Eckstein, and Philipp Werner

Phys. Rev. B 97, 245129 (2018) - Published 19 June, 2018

Nonequilibrium dynamical mean-field theory (DMFT) is one of the most powerful theoretical tools to study the dynamics in strongly correlated systems. In practice, however, the method is limited by its considerable computational cost. Here, the authors systematically investigate how the computational effort can be reduced by at least an order of magnitude while retaining high accuracy. The key idea is the controlled truncation of the time scale on which the system “remembers” its initial state. Applying this idea to paradigmatic model systems, the authors map out the optimal regimes in which this truncation yields an accurate description of the relevant observables. This approach makes fundamental long-time processes such as prethermalization and thermalization accessible to DMFT simulations.

Entanglement and quantum transport in integrable systems

Vincenzo Alba

Phys. Rev. B 97, 245135 (2018) - Published 22 June, 2018

Understanding the entanglement structure of out-of-equilibrium many-body systems is a challenging, yet revealing task. Here, the author investigates the entanglement dynamics after a quench from a piecewise homogeneous state. This is the prototypical setup for studying quantum transport. By using a generalized hydrodynamic approach for integrable models and the quasiparticle picture for the entanglement dynamics, he conjectures a formula for the entanglement production rate after joining two semi-infinite homogeneous states, as well as for the steady-state entanglement entropy of a finite region. Interestingly, both quantities are determined by the physics, describing the interface between the two reservoirs.

Pressure-induced melting of magnetic order and emergence of a new quantum state in α−RuCl3

Phys. Rev. B 97, 245149 (2018) - Published 29 June, 2018

A quantum spin liquid is an exotic quantum state of matter that does not exhibit any classical magnetic ordered ground state. The realization of such a state in actual materials is of significant importance as it would provide a path to protected states for quantum information applications and also to Majorana fermions - both areas of vigorous current activity and interest in condensed matter physics. However, no solid evidence for the existence of such materials has been established in the laboratory, despite a decades-long search. Here, the authors report the pressure-induced melting of magnetic order and emergence of a new quantum state in α-RuCl3, a candidate compound in the proximity of a quantum spin-liquid state. The high-pressure phase is found to be extremely robust against applied pressure up to ~140 GPa.

Photoluminescence and gain/absorption spectra of a driven-dissipative electron-hole-photon condensate

Ryo Hanai, Peter B. Littlewood, and Yoji Ohashi

Phys. Rev. B 97, 245302 (2018) - Published 1 June, 2018

An exciton-polariton condensate provides a unique platform to study many-body physics in an optical device. The crucial novelty of this system is the lossy nature of photons which is compensated by continuous pumping of the carriers, driving the system into an intrinsic nonequilibrium state. Here, the authors theoretically study the driven-dissipative nature of an electron-hole-photon condensate, by extending the generalized random phase approximation to the Keldysh formalism. They show that nonequilibrium effects strongly suppress quantum depletion, characterized by the suppression of the spectral weight from the negative energy branch (the “ghost branch”) in optical quantities. The results are in semiquantitative agreement with the photoluminescence experiments.

Quasiparticle tunneling in the lowest Landau level

Szymon Hennel, Patrick Scheidegger, Max Kellermeier, Andrea Hofmann, Tobias Krähenmann, Christian Reichl, Werner Wegscheider, Thomas Ihn, and Klaus Ensslin

Phys. Rev. B 97, 245305 (2018) - Published 11 June, 2018

Tunneling between two close-by edge states is a potentially powerful probe of topological order in the fractional quantum Hall effect. A fit to experimental data is believed to yield the effective charge and the interaction parameter of current-carrying quasiparticles. However, the robustness of this method has yet to be established. Here, the authors consider the well-understood state at ν=1/3 and check whether quasiparticle tunneling measures the expected parameters. While a charge of e/3 is observed, the interaction parameter is not universal, and the currently available theory cannot describe data obtained for high channel transmission. At ν=4/3, the data suggest that only an inner Laughlin edge mode contributes to tunneling.

Interacting many-body quantum systems are believed to heat up unboundedly under a periodic drive as there is no local conservation law to prevent this from happening. Here, the authors show that this belief may not be generally true. Their results indicate that under strong periodic driving quantum interference may suppress the heating and may lead to a nonthermal state, remembering properties of the initial state until infinite time. This is accounted for by the emergence of an approximately conserved local quantity. The freezing is more pronounced for smaller drive frequencies, putting it beyond the scope of conventionally used high-frequency expansions.

Truncating the memory time in nonequilibrium dynamical mean field theory calculations

Phys. Rev. B 97, 245129 (2018) - Published 19 June, 2018

Nonequilibrium dynamical mean-field theory (DMFT) is one of the most powerful theoretical tools to study the dynamics in strongly correlated systems. In practice, however, the method is limited by its considerable computational cost. Here, the authors systematically investigate how the computational effort can be reduced by at least an order of magnitude while retaining high accuracy. The key idea is the controlled truncation of the time scale on which the system “remembers” its initial state. Applying this idea to paradigmatic model systems, the authors map out the optimal regimes in which this truncation yields an accurate description of the relevant observables. This approach makes fundamental long-time processes such as prethermalization and thermalization accessible to DMFT simulations.

Phys. Rev. B 97, 245135 (2018) - Published 22 June, 2018

Understanding the entanglement structure of out-of-equilibrium many-body systems is a challenging, yet revealing task. Here, the author investigates the entanglement dynamics after a quench from a piecewise homogeneous state. This is the prototypical setup for studying quantum transport. By using a generalized hydrodynamic approach for integrable models and the quasiparticle picture for the entanglement dynamics, he conjectures a formula for the entanglement production rate after joining two semi-infinite homogeneous states, as well as for the steady-state entanglement entropy of a finite region. Interestingly, both quantities are determined by the physics, describing the interface between the two reservoirs.

A quantum spin liquid is an exotic quantum state of matter that does not exhibit any classical magnetic ordered ground state. The realization of such a state in actual materials is of significant importance as it would provide a path to protected states for quantum information applications and also to Majorana fermions - both areas of vigorous current activity and interest in condensed matter physics. However, no solid evidence for the existence of such materials has been established in the laboratory, despite a decades-long search. Here, the authors report the pressure-induced melting of magnetic order and emergence of a new quantum state in α-RuCl3, a candidate compound in the proximity of a quantum spin-liquid state. The high-pressure phase is found to be extremely robust against applied pressure up to ~140 GPa.

Phys. Rev. B 97, 245302 (2018) - Published 1 June, 2018

An exciton-polariton condensate provides a unique platform to study many-body physics in an optical device. The crucial novelty of this system is the lossy nature of photons which is compensated by continuous pumping of the carriers, driving the system into an intrinsic nonequilibrium state. Here, the authors theoretically study the driven-dissipative nature of an electron-hole-photon condensate, by extending the generalized random phase approximation to the Keldysh formalism. They show that nonequilibrium effects strongly suppress quantum depletion, characterized by the suppression of the spectral weight from the negative energy branch (the “ghost branch”) in optical quantities. The results are in semiquantitative agreement with the photoluminescence experiments.

Tunneling between two close-by edge states is a potentially powerful probe of topological order in the fractional quantum Hall effect. A fit to experimental data is believed to yield the effective charge and the interaction parameter of current-carrying quasiparticles. However, the robustness of this method has yet to be established. Here, the authors consider the well-understood state at ν=1/3 and check whether quasiparticle tunneling measures the expected parameters. While a charge of e/3 is observed, the interaction parameter is not universal, and the currently available theory cannot describe data obtained for high channel transmission. At ν=4/3, the data suggest that only an inner Laughlin edge mode contributes to tunneling.

Phys. Rev. B 97, 245416 (2018) - Published 19 June, 2018

Novel ways to manipulate electron-lattice cooling in solids are of wide interest for both fundamental and applied research. This article describes a mechanism of tunable electron-lattice cooling mediated by defects in a graphene lattice, representing resonant scatterers with energy levels close to the Dirac point. The defects produce a resonant enhancement of cooling, which is analogous to the well-known Purcell effect in optics. Namely, the emission rate of phonons is greatly enhanced when the electronic Fermi energy is tuned to match the defect resonance energy. The ability to control both the cooling rate through electronic gating and the spatial location of cooling through precise defect engineering opens a route to designing cooling pathways in nanodevices.
