Classes of metastable thermodynamic quantum time crystals

S. I. Mukhin and T. R. Galimzyanov

Phys. Rev. B 100, 081103(R) (2019) - Published 12 August, 2019

Quantum field theories of many-body systems predict “instantonic crystals” connecting degenerate thermodynamic states with classically broken symmetries. The instantons break continuous translation symmetry of Euclidean space along the axis of imaginary time. The possibility for the emergence of “thermodynamic quantum time crystals” that extremize the Euclidean action of the system appeals to the imagination. However, the authors prove here that at least two general classes of “instantonic crystals”, connecting states of Fermi systems with charge, spin, or superconducting orders can constitute neither thermodynamic equilibrium nor the ground state.

Topology and observables of the non-Hermitian Chern insulator

Mark R. Hirsbrunner, Timothy M. Philip, and Matthew J. Gilbert

Phys. Rev. B 100, 081104(R) (2019) - Published 12 August, 2019

Given the rising importance of non-Hermitian theories that describe open lossy systems, significant research has focused on studying non-Hermitian topological invariants. However, recent work suggests that related observables may no longer be quantized. Here, the authors illustrate the underlying structure of the Green’s function of non-Hermitian Hamiltonians that precludes the quantization of the Chern-Simons coefficient, resulting in the nonquantization of the Hall response of non-Hermitian Chern insulators. By showing nonquantization across a broad class of non-Hermitian Hamiltonians, the authors demonstrate the disconnect in non-Hermitian systems between a topological invariant, the Chern number, and its associated observable, the Hall conductivity.

Spinning radiation from a topological insulator

Emroz Khan and Evgenii E. Narimanov

Phys. Rev. B 100, 081408(R) (2019) - Published 22 August, 2019

Axion coupling in topological insulators dramatically changes the electromagnetic response of these materials. Here, the authors show that this coupling leads to the emergence of spin angular momentum in the associated thermal radiation where all emitted light is elliptically polarized in the same direction. In contrast to conventional thermal emitters with a structured interface, a slab of a topological insulator with a thin magnetic coating would radiate thermal photons with the same magnitude and direction of circular polarization in all emission angles.

Magic angle hierarchy in twisted graphene multilayers

Eslam Khalaf, Alex J. Kruchkov, Grigory Tarnopolsky, and Ashvin Vishwanath

Phys. Rev. B 100, 085109 (2019) - Published 2 August, 2019

The recent discovery of correlated insulating states and superconductivity in twisted bilayer graphene has opened the door to a new approach to designing correlated materials by controlling the twist angles. In this study, the authors propose a large class of graphene-based moiré heterostructures which similarly exhibit flat bands at a sequence of magic angles whose pattern is analytically related to the bilayer magic angles. The proposed setup may be experimentally more stable compared to the bilayer case and features the coexistence of a flat band with Dirac dispersing bands, potentially leading to qualitatively different types of flat-band induced correlated phases.

Generalized route to effective field theories for quantum systems with local constraints

Attila Szabó, Garry Goldstein, Claudio Castelnovo, and Alexei M. Tsvelik

Phys. Rev. B 100, 085113 (2019) - Published 5 August, 2019

Effective models featuring hard local constraints describe several strongly correlated electronic systems that exhibit interesting and exotic behavior from emergent gauge symmetries to deconfined criticality and topological order. A systematic field-theoretic approach to such models remained elusive to date, with effective theories constructed from physical insight. Here, the authors propose a general large-S path-integral formalism to obtain field theories for hard constrained Hamiltonians. They demonstrate its potential by performing a systematic study of quantum dimer models, including such on nonbipartite lattices.

Topologically protected photonic modes in composite quantum Hall/quantum spin Hall waveguides

Shukai Ma, Bo Xiao, Yang Yu, Kueifu Lai, Gennady Shvets, and Steven M. Anlage

Phys. Rev. B 100, 085118 (2019) - Published 8 August, 2019

The authors report on the creation of the first optical analog of a composite quantum Hall (QH) and quantum spin-Hall (QSH) interface that carries topologically protected modes - a heterogeneous structure that is unprecedented in condensed matter physics. The effective spin degree of freedom of the topologically protected electromagnetic modes determines their unique pathways through these systems. Experimental realizations include backscatter-free 2-port isolators, unique 3-port circulators with strong isolation, and full 4-port circulators, based on composite QH and QSH structures.

Proximity exchange effects in MoSe2 and WSe2 heterostructures with CrI3: Twist angle, layer, and gate dependence

Klaus Zollner, Paulo E. Faria Junior, and Jaroslav Fabian

Phys. Rev. B 100, 085128 (2019) - Published 16 August, 2019

Proximity effects in two-dimensional heterostructures allow to transform nonmagnetic materials into synthetic magnets that do not involve magnetic ions. Based on density functional theory calculations, the present study predicts a sizeable proximity exchange interactions, induced by ferromagnetic CrI3, in transition metal dichalcogenides. Remarkably, the exchange coupling depends qualitatively on the twist angle, while being also tunable by an electric field. The authors establish the short-range character of the proximity effect and make specific predictions for the excitonic level splittings, due to the induced exchange coupling.

Chiral twist on the high-Tc phase diagram in moiré heterostructures

Yu-Ping Lin and Rahul M. Nandkishore

Phys. Rev. B 100, 085136 (2019) - Published 26 August, 2019

Moiré heterostructures involving graphene realize a host of ill-understood insulating and superconducting phases with high tunability. In this work, the authors develop an asymptotically exact treatment of the weak-coupling instabilities in such systems at a particular doping value. The analysis predicts a remarkable high-Tc-like phase diagram where, upon doping, an exotic chiral insulator gives way to an equally exotic chiral superconductor. The results are unambiguous and independent of the details of the microscopic interactions.

Higher-order Floquet topological phases with corner and bulk bound states

Martin Rodriguez-Vega, Abhishek Kumar, and Babak Seradjeh

Phys. Rev. B 100, 085138 (2019) - Published 26 August, 2019

Periodically driven systems can be quite different from those in equilibrium. For example, vortices stirred in a fluid can trap nearby objects, such as bubbles. The authors report their theoretical discovery of new phases of a two-dimensional quantum system under periodic drive, in which nonequilibrium states are stabilized at the corners as well as within stirred vortices in the bulk. These are higher-order topological phases, exhibiting the intimate connection between corner and bulk vortex structures generated by spatiotemporal modulations.

Generalized Fourier's law for nondiffusive thermal transport: Theory and experiment

Chengyun Hua, Lucas Lindsay, Xiangwen Chen, and Austin J. Minnich

Phys. Rev. B 100, 085203 (2019) - Published 21 August, 2019

Fourier’s law, which relates the heat flux and temperature fields at macroscopic length scales, is fundamental to the mathematical description of heat transport. While it is well-known that Fourier’s law breaks down at lengths comparable to the mean free path of the heat carriers, an appropriate modification has remained unknown until now. In the present work, the authors derive analytically a generalized Fourier’s law that is valid over transport regimes spanning ballistic to diffusive. This relation shows that in the nondiffusive regime the heat flux and temperature fields not only have a nonlocal relationship but also depend on the properties of the heat source itself, a prediction that is verified by thermal spectroscopy experiments. This constitutive law provides a theoretical basis to understand nonlocal effects in the transport of heat at mesoscopic length scales.

Hole mobility of strained GaN from first principles

Samuel Poncé, Debdeep Jena, and Feliciano Giustino

Phys. Rev. B 100, 085204 (2019) - Published 29 August, 2019

Wurzite GaN possesses a low hole mobility, preventing its mass adoption for applications in high-power transistors. The authors perform predictive abinitio calculations of the phonon-limited mobility of GaN and find that hole mobilities as high as 120 cm2/Vs at room temperature could potentially be achieved by reversing the sign of the crystal-field splitting via uniaxial compressive strain or biaxial tensile strain. The experimental realization of this proposal will contribute to the development of high-power electronics based on GaN.

Non-Abelian Berry phase for open quantum systems: Topological protection versus geometric dephasing

Kyrylo Snizhko, Reinhold Egger, and Yuval Gefen

Phys. Rev. B 100, 085303 (2019) - Published 9 August, 2019

To what extent can coupling to a dissipative environment hinder the emergence of a geometric phase? And does dissipation undermine its possibly non-Abelian nature? Here, the authors show that non-Abelian geometric phase survives the presence of an environment, albeit modified. The dissipative coupling is manifest in the non-Abelian dynamics. Moreover, it gives rise to non-Abelian geometric dephasing, which may suppress or enhance coherent contributions, depending on the order of adiabatic operations.

Phonon engineering with superlattices: Generalized nanomechanical potentials

O. Ortíz, M. Esmann, and N. D. Lanzillotti-Kimura

Phys. Rev. B 100, 085430 (2019) - Published 22 August, 2019

Acoustic phonons constitute a promising platform for single-particle quantum simulations. To this end, the implementation of effective phononic potentials is a key requirement. In this work, the authors propose a method to mimic the effects of one-dimensional potentials on high-frequency acoustic phonons. Based on perturbed periodic superlattices, the theoretical study introduces nanostructures that are much more compact than previous implementations. This compactness enables the realization of experimental studies, even when absorption effects are considered.

Raman scattering from current-stabilized nonequilibrium phases in Ca2RuO4

K. Fürsich, J. Bertinshaw, P. Butler, M. Krautloher, M. Minola, and B. Keimer

Phys. Rev. B 100, 081101(R) (2019) - Published 1 August, 2019

Here, the authors study the current-stabilized nonequilibrium semimetallic and metallic phases in Ca2RuO4 by Raman light scattering. Using Raman thermometry, they find that Joule heating can be completely avoided by supplying sufficient cooling power. Additionally, they confirm the absence of long-range antiferromagnetic order and identify a substantial Fano broadening of several phonons, which suggests coupling to charge and orbital fluctuations. The results demonstrate that the semimetallic state is a genuine effect of the applied electrical current and that the current-induced phases have characteristics distinct from the equilibrium ones.

Chiral twist on the high-Tc phase diagram in moiré heterostructures

Yu-Ping Lin and Rahul M. Nandkishore

Phys. Rev. B 100, 085136 (2019) - Published 26 August, 2019

Moiré heterostructures involving graphene realize a host of ill-understood insulating and superconducting phases with high tunability. In this work, the authors develop an asymptotically exact treatment of the weak-coupling instabilities in such systems at a particular doping value. The analysis predicts a remarkable high-Tc-like phase diagram where, upon doping, an exotic chiral insulator gives way to an equally exotic chiral superconductor. The results are unambiguous and independent of the details of the microscopic interactions.

Phys. Rev. B 100, 085138 (2019) - Published 26 August, 2019

Periodically driven systems can be quite different from those in equilibrium. For example, vortices stirred in a fluid can trap nearby objects, such as bubbles. The authors report their theoretical discovery of new phases of a two-dimensional quantum system under periodic drive, in which nonequilibrium states are stabilized at the corners as well as within stirred vortices in the bulk. These are higher-order topological phases, exhibiting the intimate connection between corner and bulk vortex structures generated by spatiotemporal modulations.

Generalized Fourier's law for nondiffusive thermal transport: Theory and experiment

Chengyun Hua, Lucas Lindsay, Xiangwen Chen, and Austin J. Minnich

Phys. Rev. B 100, 085203 (2019) - Published 21 August, 2019

Fourier’s law, which relates the heat flux and temperature fields at macroscopic length scales, is fundamental to the mathematical description of heat transport. While it is well-known that Fourier’s law breaks down at lengths comparable to the mean free path of the heat carriers, an appropriate modification has remained unknown until now. In the present work, the authors derive analytically a generalized Fourier’s law that is valid over transport regimes spanning ballistic to diffusive. This relation shows that in the nondiffusive regime the heat flux and temperature fields not only have a nonlocal relationship but also depend on the properties of the heat source itself, a prediction that is verified by thermal spectroscopy experiments. This constitutive law provides a theoretical basis to understand nonlocal effects in the transport of heat at mesoscopic length scales.

Hole mobility of strained GaN from first principles

Phys. Rev. B 100, 085204 (2019) - Published 29 August, 2019

Wurzite GaN possesses a low hole mobility, preventing its mass adoption for applications in high-power transistors. The authors perform predictive abinitio calculations of the phonon-limited mobility of GaN and find that hole mobilities as high as 120 cm2/Vs at room temperature could potentially be achieved by reversing the sign of the crystal-field splitting via uniaxial compressive strain or biaxial tensile strain. The experimental realization of this proposal will contribute to the development of high-power electronics based on GaN.

Phys. Rev. B 100, 085303 (2019) - Published 9 August, 2019

To what extent can coupling to a dissipative environment hinder the emergence of a geometric phase? And does dissipation undermine its possibly non-Abelian nature? Here, the authors show that non-Abelian geometric phase survives the presence of an environment, albeit modified. The dissipative coupling is manifest in the non-Abelian dynamics. Moreover, it gives rise to non-Abelian geometric dephasing, which may suppress or enhance coherent contributions, depending on the order of adiabatic operations.

Acoustic phonons constitute a promising platform for single-particle quantum simulations. To this end, the implementation of effective phononic potentials is a key requirement. In this work, the authors propose a method to mimic the effects of one-dimensional potentials on high-frequency acoustic phonons. Based on perturbed periodic superlattices, the theoretical study introduces nanostructures that are much more compact than previous implementations. This compactness enables the realization of experimental studies, even when absorption effects are considered.
