Multiple topological nontrivial phases in strained HgxCd1xTe

Tomáš Rauch, Steven Achilles, Jürgen Henk, and Ingrid Mertig

Phys. Rev. B 96, 035124 (2017) - Published 14 July, 2017

Topological phases of multiple bands near the Fermi energy are investigated for strained HgxCd1-xTe, both from a bulk topological invariants and a surface states perspective. The main result of the paper is that nontrivial topology is induced solely by the spin-orbit coupling and not by the sp band inversion. It is obtained through the actual calculation of the topological invariants of individual bands throughout the topological phase diagram. Along with insulating topological phases, Weyl-semimetal phases have also been identified in this material.

Rich magnetoelectric phase diagrams of multiferroic single-crystal αNaFeO2

Phys. Rev. B 96, 035128 (2017) - Published 17 July, 2017

The authors have studied the multiferroic properties of a triangular lattice magnet with ferromagnetic nearest-neighbor (NN) interactions, using single-crystal α-NaFeO2 grown by hydrothermal synthesis. Despite the ferromagnetic NN interactions, this system exhibits very rich magnetoelectric phase diagrams induced by application of magnetic field. The relationship between complex magnetic ordering and ferroelectric polarization can be explained by the inverse Dzyaloshinskii-Moriya effect. Competition between antiferromagnetic second NN interactions in the triangular lattice plane and weak inter-plane interactions leads to a rich phase diagram for the crystal under study.

Spectrum of the Wilson-Fisher conformal field theory on the torus

Seth Whitsitt, Michael Schuler, Louis-Paul Henry, Andreas M. Läuchli, and Subir Sachdev

Phys. Rev. B 96, 035142 (2017) - Published 24 July, 2017

The authors study the finite-size energy spectrum of the O(N) symmetric Wilson-Fisher conformal field theory (CFT) on the spatial torus. They first perform an analytic calculation of the spectrum using the ϵ expansion with a careful treatment of the zero-momentum modes. The authors also perform exact diagonalization on several lattice Hamiltonians whose critical points are known to be described by the Wilson-Fisher CFT. Comparison of the analytic and numerical data demonstrates that the energy spectrum is a useful diagnostic for determining the universality class of a critical point. These results have applications in determining the critical behavior of more complicated many-body systems.

Evidence of a fractional quantum Hall nematic phase in a microscopic model

N. Regnault, J. Maciejko, S. A. Kivelson, and S. L. Sondhi

Phys. Rev. B 96, 035150 (2017) - Published 27 July, 2017

The fractional quantum Hall (FQH) nematic state is a conjectured state of matter in which FQH topological order coexists with spontaneously broken rotation symmetry. Recent experiments on GaAs quantum wells suggest this state, as well as the concomitant isotropic-nematic phase transition, may be realized in a two-dimensional electron gas at certain rational filling factors. Although effective field theories of the FQH nematic state have been constructed, there has been so far no explicit realization of this state as the ground state of a microscopic model of interacting electrons. The authors show via a variational approach and numerical exact diagonalization that tuning Haldane pseudopotentials in a model of interacting electrons in the lowest Landau level induces a quantum phase transition out of the isotropic Laughlin FQH liquid and into the FQH nematic state.

Optical and magnetic measurements of gyroscopically stabilized graphene nanoplatelets levitated in an ion trap

Pavel Nagornykh, Joyce E. Coppock, Jacob P. J. Murphy, and B. E. Kane

Phys. Rev. B 96, 035402 (2017) - Published 5 July, 2017

The authors present magnetic moment measurements of a levitated graphene nanoplatelet, observing two mechanisms of interaction with a magnetic field, one diamagnetic and one due to the particle’s rotation. These observations are made possible by gyroscopically stabilizing the nanoplatelet using radio-frequency electric fields, achieving control of the rotation frequency up to 100 MHz while it is held in an electric field trap at high vacuum. Levitation avoids substrate effects and clamping losses entirely, while gyroscopic stabilization provides unparalleled torque sensitivity. The method is expected to be generalizable to other two-dimensional materials and nanoparticles and may be incorporated into optomechanics experiments.

Tunable quasiparticle band gap in few-layer GaSe/graphene van der Waals heterostructures

Phys. Rev. B 96, 035407 (2017) - Published 7 July, 2017

Two-dimensional few-layered materials exhibit unique and exotic electronic properties when compared to their bulk counterparts. Here, the authors report the role of dimensionality on the electronic properties of a van der Waals GaSe/graphene heterostructure. The strong thickness dependence of the GaSe band gap is demonstrated experimentally using scanning tunneling spectroscopy. The GaSe band gap decreases as the number of layers increases due to quantum confinement effects. The particular GaSe ‘Mexican hat’ band structure is further explored by angle-resolved photoemission spectroscopy and by theoretical calculations. Interestingly, an electron transfer from graphene to GaSe has also been detected. It results in n-type doped thin GaSe films, opposite to the p-type character GaSe bulk.

Chirality blockade of Andreev reflection in a magnetic Weyl semimetal

Phys. Rev. B 96, 035437 (2017) - Published 26 July, 2017

Conduction electrons in Weyl semimetals move as massless relativistic particles with a definite chirality, meaning that the spin points parallel or antiparallel to the momentum. Such a spin-momentum locking allows for a mechanism to control Cooper-pair transfer at the interface between a magnetic Weyl semimetal and a superconductor. The authors demonstrate that Andreev reflection is fully suppressed when the internal magnetization lies in the plane of the interface. External magnetic field can activate Andreev reflection by relaxing the requirement of zero-spin transfer into the superconductor. The chiralityblockade that the team has discovered provides a phase-insensitive mechanism to control supercurrent. It is also the unique signature of a pseudoscalar superconducting pair potential.

Coupling and braiding Majorana bound states in networks defined in two-dimensional electron gases with proximity-induced superconductivity

Michael Hell, Karsten Flensberg, and Martin Leijnse

Phys. Rev. B 96, 035444 (2017) - Published 31 July, 2017

A key challenge in realizing a Majorana-based topological quantum computer is to identify a scalable platform granting easy control over networks of Majorana bound states. A promising candidate is a two-dimensional electron gas with strong spin-orbit coupling and a superconducting layer on top. Here, the authors propose two different ways of defining Majorana networks in these structures and theoretically model the basic network elements. They show that Majoranas can be exchanged (braided) by controlling their coupling with electric gates.

These observations are made possible by gyroscopically stabilizing the nanoplatelet using radio-frequency electric fields, achieving control of the rotation frequency up to 100 MHz while it is held in an electric field trap at high vacuum. Levitation avoids substrate effects and clamping losses entirely, while gyroscopic stabilization provides unparalleled torque sensitivity. The method is expected to be generalizable to other two-dimensional materials and nanoparticles and may be incorporated into optomechanics experiments.

Two-dimensional few-layered materials exhibit unique and exotic electronic properties when compared to their bulk counterparts. Here, the authors report the role of dimensionality on the electronic properties of a van der Waals GaSe/graphene heterostructure. The strong thickness dependence of the GaSe band gap is demonstrated experimentally using scanning tunneling spectroscopy. The GaSe band gap decreases as the number of layers increases due to quantum confinement effects. The particular GaSe ‘Mexican hat’ band structure is further explored by angle-resolved photoemission spectroscopy and by theoretical calculations. Interestingly, an electron transfer from graphene to GaSe has also been detected. It results in n-type doped thin GaSe films, opposite to the p-type character GaSe bulk.

Conduction electrons in Weyl semimetals move as massless relativistic particles with a definite chirality, meaning that the spin points parallel or antiparallel to the momentum. Such a spin-momentum locking allows for a mechanism to control Cooper-pair transfer at the interface between a magnetic Weyl semimetal and a superconductor. The authors demonstrate that Andreev reflection is fully suppressed when the internal magnetization lies in the plane of the interface. External magnetic field can activate Andreev reflection by relaxing the requirement of zero-spin transfer into the superconductor. The chiralityblockade that the team has discovered provides a phase-insensitive mechanism to control supercurrent. It is also the unique signature of a pseudoscalar superconducting pair potential.

A key challenge in realizing a Majorana-based topological quantum computer is to identify a scalable platform granting easy control over networks of Majorana bound states. A promising candidate is a two-dimensional electron gas with strong spin-orbit coupling and a superconducting layer on top. Here, the authors propose two different ways of defining Majorana networks in these structures and theoretically model the basic network elements. They show that Majoranas can be exchanged (braided) by controlling their coupling with electric gates.
