Anatomy of skin modes and topology in non-Hermitian systems

Ching Hua Lee and Ronny Thomale

Phys. Rev. B 99, 201103(R) (2019) - Published 8 May, 2019

Non-Hermitian systems can exhibit a counterintuitive phenomenon where a single local boundary or disorder modifies the entire spectrum, no matter how large the system is. In such cases, all bulk modes become localized “skin” modes, and usual bulk topological invariants no longer correctly predict topological boundary modes. Generalizing Laughlin’s gauge argument to complex fluxes, the authors derive a geometrical approach for the exact determination of the skin-mode spectrum. They also devise a new topological criterion for non-Hermitian particle-hole symmetric Hamiltonians based on complex analysis.

Nodal arc of disordered Dirac fermions and non-Hermitian band theory

Michał Papaj, Hiroki Isobe, and Liang Fu

Phys. Rev. B 99, 201107(R) (2019) - Published 15 May, 2019

Disordered Dirac fermions have been studied in a variety of contexts, including quantum Hall transitions, surface states of topological insulators, and graphene. Here, the authors study a new Dirac system in which the two components of the Dirac fermion are unrelated by symmetry and, hence, disorder results in two different quasiparticle lifetimes. It is demonstrated that disorder generates a nodal arc replacing the original Dirac point, thus leading to a new universality class.

Exciton condensation in quantum Hall bilayers at total filling νT=5

Zheng Zhu, Shao-Kai Jian, and D. N. Sheng

Phys. Rev. B 99, 201108(R) (2019) - Published 20 May, 2019

Quantum Hall bilayers have proven to be an inexhaustible platform for emerging exotic states and novel phase transitions in the strongly correlated arena. Here, the authors study coupled quantum Hall bilayers at half-filled first excited Landau levels by varying the layer distance. The authors find a continuous transition between the exciton superfluid phase and two copies of the Moore-Read state. This transition breaks symmetry and changes topology simultaneously, providing an exotic example of a quantum phase transition beyond the Landau paradigm.

Absence of signatures of Weyl orbits in the thickness dependence of quantum transport in cadmium arsenide

Luca Galletti, Timo Schumann, David A. Kealhofer, Manik Goyal, and Susanne Stemmer

Phys. Rev. B 99, 201401(R) (2019) - Published 1 May, 2019

In a Weyl orbit, the Fermi arc surface states on opposite surfaces of the topological semimetal are connected through bulk Weyl or Dirac nodes. Having a real-space component, these orbits are expected to accumulate a sample thickness dependent phase. Here, it is shown that small variations in the carrier density, in combination with the relative insensitivity of the low-field Hall data to such variations, does not allow for invoking Weyl orbits based on the thickness dependence for realistic samples.

Non-Hermitian higher-order topological states in nonreciprocal and reciprocal systems with their electric-circuit realization

Motohiko Ezawa

Phys. Rev. B 99, 201411(R) (2019) - Published 21 May, 2019

Nonreciprocal non-Hermitian higher-order topological skin states are realized in LC electric circuits with diodes. Here, the authors give examples with rhombus geometry of the nonreciprocal honeycomb system and rhombohedron geometry of the diamond lattice system. In the accompanying image, red balls represent zero-energy topological corner states.

All-electron fully relativistic Kohn-Sham theory for solids based on the Dirac-Coulomb Hamiltonian and Gaussian-type functions

Marius Kadek, Michal Repisky, and Kenneth Ruud

Phys. Rev. B 99, 205103 (2019) - Published 3 May, 2019

A major challenge in computational solid-state physics is the capability of first-principles theories to treat relativistic effects nonperturbatively when modeling material properties driven by atomic-core regions or the spin-orbit interaction. Such a relativistic approach is mandatory for heavy-element containing materials that often exhibit nontrivial topological properties. Here, the first formulation and implementation of a relativistic full-potential theory for solids solving the four-component Dirac-Kohn-Sham equation within local Gaussian-type bases is presented. Time-reversal symmetry is exploited in a quaternion algebra-based formalism to significantly reduce the methodological and computational complexity of the approach. The results are demonstrated to be well converged with basis sets developed for molecules.

Floquet spin and spin-orbital Hamiltonians and doublon-holon generations in periodically driven Mott insulators

Kasra Hejazi, Jianpeng Liu, and Leon Balents

Phys. Rev. B 99, 205111 (2019) - Published 9 May, 2019

Intense light can alter the electronic properties of materials through its oscillating electric field. The effects on magnetic excitations in insulators, however, are indirect, since these are neutral and do not see the electric field directly. This study reports on how exchange interactions in single- and multiorbital Mott insulators are modified by electromagnetic radiation, whose frequency is assumed to be on the order of the Mott-Hubbard gap. The latter condition results in a nonvanishing creation rate of doubly occupied sites (doublons), which necessitates taking into account the finite bandwidth of the doublon excitations, a feature which goes beyond the naïve leading order strong correlation expansion. This ultimately leads to a complex-valued exchange parameter, where the real part represents the “Floquet” spin-exchange interaction, while the imaginary part reflects the creation rate of doublons.

Scalable fermionic error correction in Majorana surface codes

Oscar Viyuela, Sagar Vijay, and Liang Fu

Phys. Rev. B 99, 205114 (2019) - Published 10 May, 2019

Quantum computers based on Majorana fermions offer intrinsic robustness due to the topological nature of these quasiparticles. However, active quantum error correction is still necessary in order to perform fully protected quantum gates and reliably store information due to the presence of unwanted errors, such as quasiparticle poisoning. Here, the authors demonstrate that using networks of interacting Majorana particles achieves a higher error tolerance than traditional qubit-based quantum computers, thereby offering potential advantages for large-scale quantum information processing.

Continuum models for twisted bilayer graphene: Effect of lattice deformation and hopping parameters

Francisco Guinea and Niels R. Walet

Phys. Rev. B 99, 205134 (2019) - Published 20 May, 2019

Twisted bilayer graphene is one of the most promising low-dimensional materials, showing both superconducting and insulating behavior. This is understood to be due to the occurrence of extremely flat bands at the magic angles, which enhances the residual interaction effects. Here, the authors show that the most common understanding of this problem neglects two important effects, the deformation of the graphene layers and the modification of electronic hopping between the atoms of the layers. A method to extract a continuum model in the presence of these effects is presented.

Nonlocal topological electromagnetic phases of matter

Todd Van Mechelen and Zubin Jacob

Phys. Rev. B 99, 205146 (2019) - Published 28 May, 2019

Topological electromagnetic phases of matter belong to a unique class of quantum phases in atomic-scale media. The ultimate origin of electromagnetic phases lies in the nonlocal Hall conductivity. Unlike their electronic counterparts, topological electromagnetic materials are manifestly bosonic and exhibit protected spin-1 edge states. To uncover the signatures of these bosonic phases, the authors introduce the microscopic theory of photonic band structure and analyze the symmetries of the atomic lattice. Beside the Chern invariant, there are also symmetry-protected topological invariants that are characterized by spin-1 eigenvalues of the electromagnetic field, as illustrated in the accompanying figure.

Bridging Hubbard model physics and quantum Hall physics in trilayer graphene/hBN moiré superlattice

Ya-Hui Zhang and T. Senthil

Phys. Rev. B 99, 205150 (2019) - Published 28 May, 2019

ABC-stacked trilayer graphene aligned with a boron nitride substrate is a fascinating correlated electron system with gate-tunable bandwidth and band topology. This paper derives an explicit lattice extended Hubbard model for the topologically trivial side. This provides a solid framework for future studies of this system. An interesting outcome is the identification of a novel physical mechanism for ferromagnetism in a Mott insulator. The paper also highlights the remarkable opportunities presented by this system for fundamental studies of the electronic Mott transition through feasible transport experiments.

Geometric responses of the Pfaffian state

Vatsal Dwivedi and Semyon Klevtsov

Phys. Rev. B 99, 205158 (2019) - Published 31 May, 2019

The universal transport coefficients of fractional quantum Hall states can be obtained from the response of trial wave functions to variations of the background geometry. The authors define and study the Pfaffian (or Moore-Read) state, which has been proposed to describe the fractional quantum Hall state at a filling fraction 52, on compact curved manifolds by means of a path integral approach. Starting from the trial wave function, they compute the electron density and the static structure factor in a large-N expansion, including an exact derivation of the gravitational anomaly contribution.

Magnetophotoluminescence of exciton Rydberg states in monolayer WSe2

Erfu Liu, Jeremiah van Baren, Takashi Taniguchi, Kenji Watanabe, Yia-Chung Chang, and Chun Hung Lui

Phys. Rev. B 99, 205420 (2019) - Published 16 May, 2019

In analogy to Rydberg states in hydrogen atoms, excitons in two-dimensional semiconductors host a series of internal states. The optical spectra of these Rydberg excitons are important to understand their diverse properties for novel optical and optoelectronic applications. Here, the authors have measured the photoluminescence spectra of 1s-5s exciton Rydberg states in ultraclean monolayer WSe2 under a magnetic field. From the spectra, they determine the g-factors, exciton radii, and binding energies of various Rydberg excitons.

Nonlocal topological electromagnetic phases of matter

Todd Van Mechelen and Zubin Jacob

Phys. Rev. B 99, 205146 (2019) - Published 28 May, 2019

Topological electromagnetic phases of matter belong to a unique class of quantum phases in atomic-scale media. The ultimate origin of electromagnetic phases lies in the nonlocal Hall conductivity. Unlike their electronic counterparts, topological electromagnetic materials are manifestly bosonic and exhibit protected spin-1 edge states. To uncover the signatures of these bosonic phases, the authors introduce the microscopic theory of photonic band structure and analyze the symmetries of the atomic lattice. Beside the Chern invariant, there are also symmetry-protected topological invariants that are characterized by spin-1 eigenvalues of the electromagnetic field, as illustrated in the accompanying figure.

Phys. Rev. B 99, 205150 (2019) - Published 28 May, 2019

ABC-stacked trilayer graphene aligned with a boron nitride substrate is a fascinating correlated electron system with gate-tunable bandwidth and band topology. This paper derives an explicit lattice extended Hubbard model for the topologically trivial side. This provides a solid framework for future studies of this system. An interesting outcome is the identification of a novel physical mechanism for ferromagnetism in a Mott insulator. The paper also highlights the remarkable opportunities presented by this system for fundamental studies of the electronic Mott transition through feasible transport experiments.

Phys. Rev. B 99, 205158 (2019) - Published 31 May, 2019

The universal transport coefficients of fractional quantum Hall states can be obtained from the response of trial wave functions to variations of the background geometry. The authors define and study the Pfaffian (or Moore-Read) state, which has been proposed to describe the fractional quantum Hall state at a filling fraction 52, on compact curved manifolds by means of a path integral approach. Starting from the trial wave function, they compute the electron density and the static structure factor in a large-N expansion, including an exact derivation of the gravitational anomaly contribution.

In analogy to Rydberg states in hydrogen atoms, excitons in two-dimensional semiconductors host a series of internal states. The optical spectra of these Rydberg excitons are important to understand their diverse properties for novel optical and optoelectronic applications. Here, the authors have measured the photoluminescence spectra of 1s-5s exciton Rydberg states in ultraclean monolayer WSe2 under a magnetic field. From the spectra, they determine the g-factors, exciton radii, and binding energies of various Rydberg excitons.
