Strong Electron-Electron Interactions of a Tomonaga--Luttinger Liquid Observed in InAs Quantum Wires

Yosuke Sato, Sadashige Matsuo, Chen-Hsuan Hsu +12

We report strong electron-electron interactions in quantum wires etched from an InAs quantum well, a material known to have strong spin-orbit interactions. We find that the current…

Difference in charge and spin dynamics in a quantum dot-lead coupled system

Tomohiro Otsuka, Takashi Nakajima, Matthieu R. Delbecq +12

We analyze time evolution of charge and spin states in a quantum dot coupled to an electric reservoir. Utilizing high-speed single-electron detection, we focus on dynamics induced…

G-factor of electrons in gate-defined quantum dots in a strong in-plane magnetic field

Peter Stano, Chen-Hsuan Hsu, Marcel Serina +3

We analyze orbital effects of an in-plane magnetic field on the spin structure of states of a gated quantum dot based in a two-dimensional electron gas. Starting with a …

Many-body quantum Monte Carlo study of 2D materials: cohesion and band gap in single-layer phosphorene

Tobias Frank, Rene Derian, Kamil Tokar +3

Quantum Monte Carlo (QMC) is applied to obtain the fundamental (quasiparticle) electronic band gap, , of a semiconducting two-dimensional (2D) phosphorene whose optical and el…

Majorana Kramers pairs in higher-order topological insulators

Chen-Hsuan Hsu, Peter Stano, Jelena Klinovaja +1

We propose a tune-free scheme to realize Kramers pairs of Majorana bound states in recently discovered higher-order topological insulators (HOTIs). We show that, by bringing two hi…

Luminescence and absorption in short period superlattices

M. F. Pereira

This paper applies analytical approximations for the luminescence of short period semiconductor superlattices and analyses the low density regime, demonstrating that the theory cle…

Orbital effects of a strong in-plane magnetic field on a gate-defined quantum dot

Peter Stano, Chen-Hsuan Hsu, Leon Camenzind +3

We theoretically investigate the orbital effects of an in-plane magnetic field on the spectrum of a quantum dot embedded in a two-dimensional electron gas (2DEG). We derive an effe…

Spectroscopy of Quantum-Dot Orbitals with In-Plane Magnetic Fields

Leon C. Camenzind, Liuqi Yu, Peter Stano +4

We show that in-plane-magnetic-field assisted spectroscopy allows extraction of the in-plane orientation and full 3D shape of the quantum mechanical orbitals of a single electron G…
