Three-dimensional topological ferroelectrics
Haohao Sheng, Sheng Zhang, Zhong Fang +2
Three-dimensional (3D) topological ferroelectric (FE) insulators, in which topological and FE orders naturally coexist, enable field-controlled spintronic devices. In this work, we…
Majorana Zero Modes and Topological Nature in Bi2Ta3S6-family Superconductors
Yue Xie, Zhilong Yang, Ruihan Zhang +7
In this work, we report that Bi2Ta3S6-family superconductors exhibit nontrivial band topology. They possess a natural quantum-well structure consisting of alternating stacks of TaS…
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…
Axion insulator, Weyl points, quantum anomalous Hall effect and magnetic topological phase transition in Eu3In2As4
Jingyu Yao, Ruihan Zhang, Sheng Zhang +5
The magnetic topological phases attract much interest, such as the axion insulator, higher-order topology, Weyl semimetals, and the quantum anomalous Hall effect (QAHE). Here, we p…
VASP2KP: kp models and Lande g-factors from ab initio calculations
Sheng Zhang, Haohao Sheng, Zhi-Da Song +8
The method is significant in condensed matter physics for the compact and analytical Hamiltonian. In the presence of magnetic field, it is described by the effective Zee…
