IRSSG: An Open-Source Software Package for Spin Space Groups
Sheng Zhang, Ziyin Song, Zhong Fang +2
We present an open-source software package IRSSG for investigating magnetic systems with spin space groups (SSGs). The package works within the density functional theory (DFT) fram…
Spin-polarized triplet excitonic insulators in Ta3X8 (X=I, Br) monolayers
Haohao Sheng, Jingyu Yao, Sheng Zhang +5
Bose-Einstein condensation of spin-polarized triplet excitons can give rise to an intriguing spin supercurrent, enabling experimental detection of exciton condensation. In this wor…
Optical Excitations of Flat Bands Induced by Exciton Condensation in TaPdTe
Shaohui Yi, Zhiyu Liao, Chenhao Liang +10
We report on the charge dynamics of TaPdTe using temperature-dependent optical spectroscopy with polarized light. We observe a metal-insulator transition characterized…
Polarization-induced Quantum Spin Hall Insulator and Topological Devices in InAs Quantum Wells
Chenhao Liang, Sheng Zhang, Haohao Sheng +4
In this work, we predict the emergence of a quantum spin Hall insulator (QSHI) in conventional semiconductors, specifically InAs quantum wells, driven by a built-in polarization fi…
