Photocurrents in Weyl semimetals

Ching-Kit Chan, Netanel H. Lindner, Gil Refael, and Patrick A. Lee

Phys. Rev. B 95, 041104(R) (2017) - Published 13 January, 2017

The discovery of topological matter should be an opportunity for revolutionizing electronic devices. Nevertheless, for all their unique properties, to date there are limited feasible devices or applications based on topological materials. The work here recognizes that topological Weyl semimetal materials, through their protected gap closing and spin-orbit locking, could be used to detect low-frequency infrared radiation. Detecting infrared light electrically beyond a ten-micron wavelength is rather difficult with few ready made commercial solutions. The authors find that Weyl semimetals could provide an ideal solution for detecting mid- and far-infrared light even at room temperature. In this work, they describe the conditions of the materials to be effective photodetectors (noncentrosymmetry, doping levels etc.) and provide a detailed analysis of this photovoltaic effect.

Quantum oscillations without magnetic field

Tianyu Liu, D. I. Pikulin, and M. Franz

Phys. Rev. B 95, 041201(R) (2017) - Published 9 January, 2017

Quantum oscillations are the fundamental measurement made when studying metals and semimetals. They provide information about the Fermi surface by measuring interference of particles drifting around it in a magnetic field. So far it was only possible to measure them by applying an external magnetic field. Here, the authors argue that the deformation of the Dirac/Weyl semimetal can produce a strong enough pseudo-magnetic field to measure quantum oscillations in the strength of the strain. They argue that the effect of the strain is identical to the effect of the real magnetic field at energies close to the Dirac/Weyl points. They propose a setup in which the strain can be tuned continuously, and in which the quantum oscillations can be first observed in the complete absence of a magnetic field.

Magnetoresistance and quantum oscillations of an electrostatically tuned semimetal-to-metal transition in ultrathin WTe2

Valla Fatemi, Quinn D. Gibson, Kenji Watanabe, Takashi Taniguchi, Robert J. Cava, and Pablo Jarillo-Herrero

Phys. Rev. B 95, 041410(R) (2017) - Published 30 January, 2017

Here, the authors extend the study of semimetallic WTe2 to the 2D limit, utilizing new fabrication schemes that preserve sample quality to create high-mobility electronic transport devices from few-layer thick crystals, previously found to be electrically insulating. The large magnetoresistance persists in these samples and can be turned off by electrostatically tuning the system to a simple-metal (noncompensated) regime. Furthermore, the semimetallic magnetoresistance is found to follow a density-independent subquadratic power law, a topic for future study. Finally, quantum oscillations are also analyzed as a function of total carrier density, providing the first insights into the band structure of ultrathin WTe2.

Exactly soluble model of boundary degeneracy

Sriram Ganeshan, Alexey V. Gorshkov, Victor Gurarie, and Victor M. Galitski

Phys. Rev. B 95, 045309 (2017) - Published 25 January, 2017

Engineering topological degeneracy within an experimentally accessible platform has been an active area of research with applications towards the pursuit of universal topological quantum computation. In this work, the authors consider Abelian fractional quantum spin Hall states with multiply connected gapped boundaries. Such a system manifests topological degeneracy (also dubbed “boundary degeneracy”) and in principle can realize universal quantum computation with no superconducting proximity required. The authors construct an exactly soluble model manifesting this topological degeneracy and solve it within Hamiltonian formalism, which is a natural framework to quantify the Hilbert space structure associated with this degenerate subspace. Furthermore, this platform is accessible within experiments and can be created by applying a depletion gate to the quantum spin Hall material and using a spin-mixing process realized by generic magnetic impurities that gap out the edge modes.

Three-boson bound states in two dimensions

Tianhao Ren and Igor Aleiner

Phys. Rev. B 95, 045401 (2017) - Published 3 January, 2017

The presence of few-body bound states is an important issue in the study of interacting bosonic systems due to the instability it introduces into the condensation. The problem is more interesting in two dimensions because the system can host only a finite number of bound states, in contrast to the Efimov effect in three dimensions. The authors considered a two-component bosonic system in two dimensions, with repulsive intra- and attractive inter-species interactions. They found that there is only one three-particle bound state and the binding energies for various scattering lengths fall on an universal curve, where the microscopic details are of no relevance. Their conclusion is pertinent for various systems such as excitons in quantum well structures and bosonic dipoles in bilayer geometries. They developed an efficient renormalization group type method, capable of handling both short- and long- range physics and free of numerical instabilities. This method also makes use of the Hopf coordinates and running basis to reduce the proliferation of hyperspherical harmonics appearing in alternative approaches, yielding significant saving in numerical implementations.

Analytical solutions of the two-dimensional Dirac equation for a topological channel intersection

J. R. Anglin and A. Schulz

Phys. Rev. B 95, 045430 (2017) - Published 30 January, 2017

What happens to the edge states when two edges intersect? The authors answer this question for the case in which the topologically protected edge states are the quasi-one-dimensional bound states that propagate unidirectionally under the two-dimensional Dirac equation, if it includes an inhomogeneous potential term that changes sign across a zero line. These “zero line modes” are bound to the line along which the potential vanishes, and so if the potential has a “checkerboard” form, such that two zero lines cross, then the question becomes: what happens to the zero line modes at the intersection? By finding an exact integral representation for the two-dimensional Dirac energy eigenstates, the authors show that the eigenstates take surprisingly narrow “T-junction” forms, so that incoming wave packets split coherently at the intersection into two outgoing packets, while remaining tightly bound to the zero lines. The intersection thereby acts as a beam splitter for zero line modes.

Engineering topological degeneracy within an experimentally accessible platform has been an active area of research with applications towards the pursuit of universal topological quantum computation. In this work, the authors consider Abelian fractional quantum spin Hall states with multiply connected gapped boundaries. Such a system manifests topological degeneracy (also dubbed “boundary degeneracy”) and in principle can realize universal quantum computation with no superconducting proximity required. The authors construct an exactly soluble model manifesting this topological degeneracy and solve it within Hamiltonian formalism, which is a natural framework to quantify the Hilbert space structure associated with this degenerate subspace. Furthermore, this platform is accessible within experiments and can be created by applying a depletion gate to the quantum spin Hall material and using a spin-mixing process realized by generic magnetic impurities that gap out the edge modes.

Three-boson bound states in two dimensions

Phys. Rev. B 95, 045401 (2017) - Published 3 January, 2017

The presence of few-body bound states is an important issue in the study of interacting bosonic systems due to the instability it introduces into the condensation. The problem is more interesting in two dimensions because the system can host only a finite number of bound states, in contrast to the Efimov effect in three dimensions. The authors considered a two-component bosonic system in two dimensions, with repulsive intra- and attractive inter-species interactions. They found that there is only one three-particle bound state and the binding energies for various scattering lengths fall on an universal curve, where the microscopic details are of no relevance. Their conclusion is pertinent for various systems such as excitons in quantum well structures and bosonic dipoles in bilayer geometries. They developed an efficient renormalization group type method, capable of handling both short- and long- range physics and free of numerical instabilities. This method also makes use of the Hopf coordinates and running basis to reduce the proliferation of hyperspherical harmonics appearing in alternative approaches, yielding significant saving in numerical implementations.

What happens to the edge states when two edges intersect? The authors answer this question for the case in which the topologically protected edge states are the quasi-one-dimensional bound states that propagate unidirectionally under the two-dimensional Dirac equation, if it includes an inhomogeneous potential term that changes sign across a zero line. These “zero line modes” are bound to the line along which the potential vanishes, and so if the potential has a “checkerboard” form, such that two zero lines cross, then the question becomes: what happens to the zero line modes at the intersection? By finding an exact integral representation for the two-dimensional Dirac energy eigenstates, the authors show that the eigenstates take surprisingly narrow “T-junction” forms, so that incoming wave packets split coherently at the intersection into two outgoing packets, while remaining tightly bound to the zero lines. The intersection thereby acts as a beam splitter for zero line modes.
