Experimental realization of a polariton beam amplifier

Dominik Niemietz, Johannes Schmutzler, Przemyslaw Lewandowski, Karol Winkler, Marc Aßmann, Stefan Schumacher, Sebastian Brodbeck, Martin Kamp, Christian Schneider, Sven Höfling, and Manfred Bayer

Phys. Rev. B 93, 235301 (2016) - Published 1 June, 2016

For polariton condensates, nonresonant excitation creates carriers that act both as a repulsive potential and a gain medium for the condensate. The repulsive potential allows for direct imprinting of functional optical elements and simple circuits based on flowing polaritons just by shaping the excitation beam. However, extended geometries will also require amplification of the polariton beam. Another nonresonant pump beam may act as an amplifier, but will necessarily also result in an undesired deflection of the traveling polariton beam. The authors show that a deflectionless amplifier can be realized by embedding the amplification beam in a photonic trap that cancels the repulsive potential created by the amplification beam. This work emphasizes the potential of polariton condensates as a platform for reconfigurable optical circuits.

Ising tricriticality in the extended Hubbard model with bond dimerization

Satoshi Ejima, Fabian H. L. Essler, Florian Lange, and Holger Fehske

Phys. Rev. B 93, 235118 (2016) - Published 10 June, 2016

The tricritical Ising universality class emerges at the end point of a line of continuous Ising phase transitions, above which the transition is first order. In 1+1 dimensions, it is described by the second minimal model of conformal field theory (CFT) with central charge c=7/10. Recently, there has been a revival of interest in the tricritical Ising model due to its emergent space-time supersymmetry. Combining numerical (infinite density-matrix renormalization group) and field theoretical (bosonization and CFT) techniques, there authors demonstrate here that Ising tricriticality occurs in a paradigmatic extended one dimensional Hubbard model with explicit bond dimerization. The low-energy sector can be described by a triple sine-Gordon model, which, in the transition region, reduces to the tricritical Ising CFT. The theoretically predicted decay of various two-point correlation functions is found to be in excellent agreement with the density-matrix renormalization group data.

Mott physics and spin fluctuations: A functional viewpoint

Thomas Ayral and Olivier Parcollet

Phys. Rev. B 93, 235124 (2016) - Published 14 June, 2016

Two important scenarios have been put forth to explain high-temperature superconductivity. One scenario emphasizes, following Philip W. Anderson, that for many high-Tc superconductors their undoped parent compounds are Mott insulators, with local physics playing a major role. Another scenario stresses instead the importance of spin fluctuations near a quantum critical point. In this work, the authors reconcile both viewpoints by constructing a functional of the Green’s function of the electron (G), of the fluctuations (W) and of the vertex that couples the two (Λ). In the approach presented by the authors, Mott physics as well as the charge and spin fluctuations are taken into account in the description of correlations. This is done at a computational cost comparable to that of the dynamical mean field theory, making the method suitable for multiorbital extensions.

Origin of dissipative Fermi arc transport in Weyl semimetals

E. V. Gorbar, V. A. Miransky, I. A. Shovkovy, and P. O. Sukhachov

Phys. Rev. B 93, 235127 (2016) - Published 15 June, 2016

The existence of the surface Fermi arc states is a signature property of the Weyl semimetals. In view of their one-dimensional chiral nature, one might naively expect that the corresponding surface transport is nondissipative. In a drastic contrast to such an expectation, the authors show here that the dynamics of the chiral surface states is dissipative in semimetals. In the presence of impurities, the origin of the dissipation is the scattering of surface Fermi arc states into the bulk of the semimetal. The gapless spectrum of the bulk states in semimetals is the key feature that allows such processes to happen. By taking into account all scattering processes, the authors perform a model calculation of the electric conductivity of the surface Fermi arc states.

Spectral functions of the uniform electron gas via coupled-cluster theory and comparison to the GW and related approximations

James McClain, Johannes Lischner, Thomas Watson, Devin A. Matthews, Enrico Ronca, Steven G. Louie, Timothy C. Berkelbach, and Garnet Kin-Lic Chan

Phys. Rev. B 93, 235139 (2016) - Published 20 June, 2016

Coupled-cluster theory is a “gold standard” of molecular quantum chemistry, but has only recently been extended to condensed-phase systems. In this work, excited-state coupled-cluster techniques are brought to bear on the spectral function of the uniform electron gas. The diagrammatic content of coupled-cluster theory goes beyond that of the GW approximation, which has become a canonical approach in first-principles condensed-matter physics. Benchmark calculations demonstrate that the coupled-cluster results are more accurate than those of GW-based approaches, insensitive to the mean-field reference, and systematically improvable towards the exact result. Calculations on large systems approaching the thermodynamic limit reveal an accurate quasiparticle bandwidth as well as plasmonic satellite structure in the core-hole spectral function.

History dependence of the magnetic properties of single-crystal Fe1−xCoxSi

A. Bauer, M. Garst, and C. Pfleiderer

Phys. Rev. B 93, 235144 (2016) - Published 21 June, 2016

Cubic chiral magnets crystallizing in space group P213 give rise to a spin structure of nontrivial topology, the so-called skyrmion lattice. The strongly doped semiconductor Fe1-xCoxSi is a fascinating member of this material class of compounds as it exhibits helimagnetism over a wide compositional range. The authors study the magnetic properties of this itinerant magnet for different values of x, combine their results with previous reports, and infer the magnetic phase diagrams. The latter are rather isotropic but depend on the field and temperature history. In particular, when cooled in an applied magnetic field, the skyrmion lattice may persist down to lowest temperatures. This history dependence, in combination with the variation of temperature, field, and length scale of the magnetic order by means of compositional tuning, makes Fe1-xCoxSi an excellent material for future experiments studying skyrmions.

Nature of composite fermions and the role of particle-hole symmetry: A microscopic account

Ajit C. Balram and J. K. Jain

Phys. Rev. B 93, 235152 (2016) - Published 27 June, 2016

Motivated by the particle-hole symmetry at the half-filled lowest Landau level, many articles have taken the point of view, following D. T. Son, that composite fermions are Dirac particles and their Fermi sea is akin to that occurring at the surface of a three dimensional topological insulator. This presents a paradox, because the microscopic theory of composite fermions, which treats composite fermions as non-relativistic particles, has been confirmed in great detail. The authors discuss what features of the Dirac-composite fermion view can be reconciled with the microscopic theory. They also show how particle-hole symmetry can emerge in the Chern-Simons formulation of composite fermions.

In situ hard x-ray photoemission spectroscopy of barrier-height control at metal/PMN-PT interfaces

Phys. Rev. B 93, 235415 (2016) - Published 10 June, 2016

Ferroelectrics exhibit switchable spontaneous polarization, a functionality that can be harnessed in nonvolatile memory devices. The main characteristics of these devices are governed by the electronic band alignment at the interfaces, particularly at the metallic contacts. Here, the authors study such an interface using state-of-the-art high-energy x-ray photoelectron spectroscopy, with in situ polarization reversal achieved by applying poling voltage. They confirm a result central to the physics of ferroelectric devices: an electrode-dependent potential drop at the interface that is linear in the spontaneous polarization. They also reveal a novel effect: electric-field-dependent increase of the energy offset due to the field-induced strain in the ferroelectric material.

Conductance of a proximitized nanowire in the Coulomb blockade regime

B. van Heck, R. M. Lutchyn, and L. I. Glazman

Phys. Rev. B 93, 235431 (2016) - Published 20 June, 2016

The search for Majorana bound states, motivated by the prospect of discovering non-Abelian exchange statistics and developing topological quantum computing, is an ongoing challenge in condensed matter physics. Crafting a wire hosting Majorana states is not a trivial task, requiring great care in the choice of materials and in the device design. Experimentalists rely on the electron transport measurements to characterize the devices. It is therefore important to have a detailed theory for interpreting the experimental data and reliably detecting the nontrivial (topological) superconductivity needed for the appearance of Majorana states. Here, the authors have developed such a theory for short small-capacitance wires. In such wires, the apperance of Majorana states coexists with the effects of single-electron charging. The theory here provides quantitative results for the electric conduction of wires in these conditions and provides guidance for those in the field seeking understanding of important recent experiments, as well as those designing the future ones.

For polariton condensates, nonresonant excitation creates carriers that act both as a repulsive potential and a gain medium for the condensate. The repulsive potential allows for direct imprinting of functional optical elements and simple circuits based on flowing polaritons just by shaping the excitation beam. However, extended geometries will also require amplification of the polariton beam. Another nonresonant pump beam may act as an amplifier, but will necessarily also result in an undesired deflection of the traveling polariton beam. The authors show that a deflectionless amplifier can be realized by embedding the amplification beam in a photonic trap that cancels the repulsive potential created by the amplification beam. This work emphasizes the potential of polariton condensates as a platform for reconfigurable optical circuits.

Ferroelectrics exhibit switchable spontaneous polarization, a functionality that can be harnessed in nonvolatile memory devices. The main characteristics of these devices are governed by the electronic band alignment at the interfaces, particularly at the metallic contacts. Here, the authors study such an interface using state-of-the-art high-energy x-ray photoelectron spectroscopy, with in situ polarization reversal achieved by applying poling voltage. They confirm a result central to the physics of ferroelectric devices: an electrode-dependent potential drop at the interface that is linear in the spontaneous polarization. They also reveal a novel effect: electric-field-dependent increase of the energy offset due to the field-induced strain in the ferroelectric material.

The search for Majorana bound states, motivated by the prospect of discovering non-Abelian exchange statistics and developing topological quantum computing, is an ongoing challenge in condensed matter physics. Crafting a wire hosting Majorana states is not a trivial task, requiring great care in the choice of materials and in the device design. Experimentalists rely on the electron transport measurements to characterize the devices. It is therefore important to have a detailed theory for interpreting the experimental data and reliably detecting the nontrivial (topological) superconductivity needed for the appearance of Majorana states. Here, the authors have developed such a theory for short small-capacitance wires. In such wires, the apperance of Majorana states coexists with the effects of single-electron charging. The theory here provides quantitative results for the electric conduction of wires in these conditions and provides guidance for those in the field seeking understanding of important recent experiments, as well as those designing the future ones.
