Anisotropic longitudinal optical conductivities of tilted Dirac bands in 1T-MoS

Chao-Yang Tan, Chang-Xu Yan, Yong-Hong Zhao +2

1T-MoS exhibits valley-spin-polarized tilted Dirac bands in the presence of external vertical electric field and undergoes a topological phase transition between the t…

Nonlinear level attraction of cavity axion polariton in antiferromagnetic topological insulator

Yang Xiao, Huaiqiang Wang, Dinghui Wang +7

Strong coupling between cavity photons and various excitations in condensed matters boosts the field of light-matter interaction and generates several exciting sub-fields, such as…

Charge carrier inversion in a doped thin film organic semiconductor island

Zeno Schumacher, Rasa Rejali, Megan Cowie +3

Inducing an inversion layer in organic semiconductors is a highly nontrivial, but critical, achievement for producing organic field-effect transistor (OFET) devices, which rely on…

Pseudospin-electric coupling for holes beyond the envelope-function approximation

Pericles Philippopoulos, Stefano Chesi, Dimitrie Culcer +1

In the envelope-function approximation, interband transitions produced by electric fields are neglected. However, electric fields may lead to a spatially local (-independent) co…

Balancing coherent and dissipative dynamics in a central-spin system

A. Ricottone, Y. N. Fang, W. A. Coish

The average time required for an open quantum system to reach a steady state (the steady-state time) is generally determined through a competition of coherent and incoherent (dissi…

Second-order topological insulator under strong magnetic field: Landau levels, Zeeman effect, and magnetotransport

B. A. Levitan, T. Pereg-Barnea

We study a three-dimensional chiral second order topological insulator (SOTI) subject to a magnetic field. Via its gauge field, the applied magnetic field influences the electronic…

Superradiant-like dynamics by electron shuttling on a nuclear-spin island

Yi-Nan Fang, Ying-Dan Wang, Rosario Fazio +1

We investigate superradiant-like dynamics of the nuclear-spin bath in a single-electron quantum dot, by considering electrons cyclically shuttling on/off an isotopically enriched `…

First-principles hyperfine tensors for electrons and holes in GaAs and silicon

Pericles Philippopoulos, Stefano Chesi, W. A. Coish

Understanding (and controlling) hyperfine interactions in semiconductor nanostructures is important for fundamental studies of material properties as well as for quantum informatio…
