Topological quadrupolar semimetals

Mao Lin and Taylor L. Hughes

Phys. Rev. B 98, 241103(R) (2018) - Published 3 December, 2018

Conventional topological semimetals are characterized by the energy momentum separation of the bulk nodes in the energy spectrum. Here, the authors demonstrate a few types of topological semimetals that are gapped in the bulk, but host one or a half of a Dirac semimetal on multiple surfaces. They show that these semimetals can be characterized by the bulk nodes in the hybrid Wannier spectrum, rather than the energy spectrum. This works points to a new direction in studying the higher order topology in semimetallic systems.

Cavity optomagnonics with magnetic textures: Coupling a magnetic vortex to light

Jasmin Graf, Hannes Pfeifer, Florian Marquardt, and Silvia Viola Kusminskiy

Phys. Rev. B 98, 241406(R) (2018) - Published 5 December, 2018

A unique feature of cavity optomagnonics is the possibility of coherently coupling light to spin excitations on top of magnetic textures. Here, the authors propose a cavity-optomagnonic system with a nonhomogeneous magnetic ground state, namely, a vortex in a magnetic microdisc. Using both analytical and computational methods, they study the cavity-enhanced coupling between optical whispering gallery modes and magnon modes, localized at the vortex. The results, both in terms of value and tunability of the coupling, point to the promise of engineered optomagnonic systems for quantum information platforms.

Strong correlations and d+id superconductivity in twisted bilayer graphene

Dante M. Kennes, Johannes Lischner, and Christoph Karrasch

Phys. Rev. B 98, 241407(R) (2018) - Published 17 December, 2018

Recently, the experimental realization of flat bands in twisted bilayer graphene has attracted much attention as in these systems the kinetic energy is almost fully quenched, giving rise to prominent interaction effects. Indeed, experimental indications for correlation-induced insulating as well as superconducting phases show a striking similarity to the physics of unconventional high-Tc superconductors. Here, the authors employ an unbiased functional renormalization group scheme to connect to these findings from a theoretical side. A topological d-wave superconducting state as well as insulating behavior are found, depending on the parameters of the model.

Cooling by Cooper pair splitting

Rafael Sánchez, Pablo Burset, and Alfredo Levy Yeyati

Phys. Rev. B 98, 241414(R) (2018) - Published 28 December, 2018

When the two electrons from a Cooper pair are separated into different reservoirs, the heat flow between the reservoirs is reverted, providing a quantum refrigerator. The process can be also used to define a nonlocal thermoelectric power generator. This is ultimately possible due to the quantum correlations of the pair. It, therefore, constitutes an experimentally accessible proposal of an entanglement-based quantum heat engine, able to optimally extract thermodynamic work from quantum many-body states.

Quantum critical behavior of two-dimensional Fermi systems with quadratic band touching

Shouryya Ray, Matthias Vojta, and Lukas Janssen

Phys. Rev. B 98, 245128 (2018) - Published 19 December, 2018

At low temperatures, isotropic two-dimensional Fermi systems with quadratic band touching are unstable with respect to a symmetry-broken ground state when interactions are taken into account. Here, the authors demonstrate that in a setup with threefold symmetry only - as realized, for instance, in bilayer graphene - interactions induce a splitting of the quadratic band touching into four Dirac cones. This shifts the instability to a finite interaction strength and leads to a quantum critical point with emergent Lorentz invariance.

Lorentz ratio of a compensated metal

Songci Li and Dmitrii L. Maslov

Phys. Rev. B 98, 245134 (2018) - Published 21 December, 2018

Violation of the Wiedemann-Franz law in a metal can be quantified by comparing the Lorentz ratio with the universal Sommerfeld constant. Here, the authors obtain the Lorentz ratio of a clean compensated metal with carrier interaction as the dominant scattering mechanism by solving exactly a system of coupled kinetic equations. The Lorentz ratio is shown to assume a particular simple form in the forward-scattering limit, in which it can be arbitrarily small compared to the Sommerfeld constant. The same result can also be obtained without recourse to an exact solution. The authors discuss how a strong downward violation of the Wiedemann-Franz law in a type-II Weyl semimetal WP2 is explained within the proposed model.

Finite-wave-vector electromagnetic response in lattice quantum Hall systems

Fenner Harper, David Bauer, T. S. Jackson, and Rahul Roy

Phys. Rev. B 98, 245303 (2018) - Published 6 December, 2018

In a quantum Hall system, the finite-wave-vector Hall conductivity displays an intriguing dependence on the Hall viscosity. Here, the authors study this connection for quantum Hall systems on a lattice and find that the neat continuum relation breaks down. In the process, they introduce a universal formalism for studying lattice quantum Hall systems and find that, in the low flux density limit, generic lattice wave functions connect smoothly to the Landau levels of the continuum. They also introduce a quantum mechanical method for calculating the electromagnetic response of such systems.

Topological zero-line modes in folded bilayer graphene

Tao Hou, Guanghui Cheng, Wang-Kong Tse, Changgan Zeng, and Zhenhua Qiao

Phys. Rev. B 98, 245417 (2018) - Published 19 December, 2018

A folded bilayer graphene device as an experimentally realizable platform to produce one-dimensional topological zero-line modes is proposed. The new scheme has the advantage that it completely obviates the conventional approach, which relies on the precise alignment of split gates, and is supported by the experimental fabrication of folded bilayer graphene with a well-controlled folding angle. These findings open up a new field for the application of folded graphene, and pave the way to realize low-power-consuming topological quantum devices.

Finite-wave-vector electromagnetic response in lattice quantum Hall systems

Phys. Rev. B 98, 245303 (2018) - Published 6 December, 2018

In a quantum Hall system, the finite-wave-vector Hall conductivity displays an intriguing dependence on the Hall viscosity. Here, the authors study this connection for quantum Hall systems on a lattice and find that the neat continuum relation breaks down. In the process, they introduce a universal formalism for studying lattice quantum Hall systems and find that, in the low flux density limit, generic lattice wave functions connect smoothly to the Landau levels of the continuum. They also introduce a quantum mechanical method for calculating the electromagnetic response of such systems.

Phys. Rev. B 98, 245417 (2018) - Published 19 December, 2018

A folded bilayer graphene device as an experimentally realizable platform to produce one-dimensional topological zero-line modes is proposed. The new scheme has the advantage that it completely obviates the conventional approach, which relies on the precise alignment of split gates, and is supported by the experimental fabrication of folded bilayer graphene with a well-controlled folding angle. These findings open up a new field for the application of folded graphene, and pave the way to realize low-power-consuming topological quantum devices.
