Tunnelling theory of Weyl semimetals in proximity to a metallic band

L. Goutte, T. Pereg-Barnea

We study the effects of tunnelling on the band structure and Fermi arc of a time-reversal broken Weyl semimetal (WSM). When coupled to a non-magnetic parabolic band, the WSM's chir…

Non-linear Transport Phenomena and Current-induced Hydrodynamics in Ultra-high Mobility Two-dimensional Electron Gas

Zitong Wang, Michael Hilke, Norm Fong +4

We report on non-linear transport phenomena at high filling factor and DC current-induced electronic hydrodynamics in an ultra-high mobility (mu=20x10^6 cm^2/Vs) two-dimensional el…

Optimizing the transport of Majorana zero modes in one-dimensional topological superconductors

Bill P. Truong, Kartiek Agarwal, T. Pereg-Barnea

Topological quantum computing is based on the notion of braiding non-Abelian anyons, such as Majorana zero modes (MZMs), to perform gate operations. A crucial building block of the…

Recent advances in hole-spin qubits

Yinan Fang, Pericles Philippopoulos, Dimitrie Culcer +2

In recent years, hole-spin qubits based on semiconductor quantum dots have advanced at a rapid pace. We first review the main potential advantages of these hole-spin qubits with re…

Effects of spatial dimensionality and band tilting on the longitudinal optical conductivities in Dirac bands

Jian-Tong Hou, Chang-Xu Yan, Chao-Yang Tan +4

We report a unified theory based on linear response, for analyzing the longitudinal optical conductivity (LOC) of materials with tilted Dirac cones. Depending on the tilt parameter…

Quadrupolar photovoltaic effect in the terahertz range in a two-dimensional spin-3/2 hole system

Mohsen Farokhnezhad, W. A. Coish, Reza Asgari +1

We identify a strong photovoltaic response due to the non-linear optical transition between heavy and light hole sub-bands enabled by T_d-symmetry in a quantum well, which we term…

Generalized fast quasi-adiabatic population transfer for improved qubit readout, shuttling, and noise mitigation

F. Fehse, M. David, M. Pioro-Ladrière +1

Population-transfer schemes are commonly used to convert information robustly stored in some quantum system for manipulation and memory into more macroscopic degrees of freedom for…

Semiclassical magnetotransport including the effects of the Berry curvature and Lorentz force

Seungchan Woo, Brett Min, Hongki Min

In topological semimetals and insulators, negative longitudinal magnetoresistance and angle-dependent planar Hall effect have been reported arising from the Berry curvature. Using…
