Entropy-Driven Structural Phase Transition in NbCl via Density Functional Theory and an Effective Model
Chenjie Zhu, Shuai Zhang, Zhong Fang +3
As a prototypical flat-band cluster Mott insulator on an effective triangular lattice, NbCl is a potential candidate for hosting a quantum spin liquid (QSL) state. Neverthe…
Percolation from Quantum Metric in Flat-Band Delocalization
Bo Yin, Zhijun Wang, Quansheng Wu
The quantum metric is a fundamental ingredient of band quantum geometry and has recently at tracted intense interest, with most of its transport signatures appearing in the intrins…
Nonsymmorphic Time-Reversal-Doubled Axion Insulators
Yue Xie, Haohao Sheng, Quansheng Wu +4
The axion insulator exhibits a topological magnetoelectric effect characterized by an axion angle , while the time-reversal-doubled axion insulator (T-DAXI) can be viewed as t…
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…
Growth and hydrostatic-pressure study of a type-II superconductor BiTaS single crystal
Li Chenglin, Yang Yaling, Yang Zhilong +9
We report the growth and physical properties of single-crystalline BiTaS crystallizing in space group, which comprises alternating Ta-S layers and Bi layers…
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…
Manipulation of topological phase transitions and the mechanism of magnetic interactions in Eu-based Zintl-phase materials
Bo-Xuan Li, Ziyin Song, Zhong Fang +2
Various topological phases, including topological insulators, topological semimetals, and topological superconductors, along with the controllable topological phase transitions, ha…
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…
