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…
Coexistence of topologically nontrivial and trivial insulating states in topological Anderson Chern insulator
Bo Yin, Yan Zhang, Anqi Wang +3
The interplay between disorder and topology has become a central theme in condensed matter physics. Disorder can not only destroy topological phases but also induce them, as exempl…
Disentangling Anomalous Hall Effect Mechanisms and Extra Symmetry Protection in Altermagnetic Systems
Yuansheng Bu, Ziyin Song, Zhong Fang +2
We investigate the evolution of Anomalous Hall Conductivity (AHC) in a coplanar and collinear antiferromagnetic system with varying spin canting angles. A tight-binding model based…
General First-Principles Approach to Crystals in Finite Magnetic Fields
Chengye Lü, Yingwei Chen, Yuzhi Wang +5
We introduce a general first-principles methodology for computing electronic structure in a finite uniform magnetic field which allows for an arbitrary rational magnetic flux and n…
Topological nontrivial berry phase in altermagnet CrSb
Jianhua Du, Xin Peng, Yuzhi Wang +12
The study of topological properties in magnetic materials has long been one of the forefront research areas in condensed matter physics. CrSb, as a prototypical candidate material…
A combined First-principles and Boltzmann transport theory methodology for studying magnetotransport in magnetic materials
Zhihao Liu, Shengnan Zhang, Zhong Fang +2
Unusual magnetotransport behaviors, such as temperature-dependent negative magnetoresistance (MR) and bowtie-shaped MR, have puzzled us for a long time. Although several mechanisms…
