Calculated magnetic exchange interactions in Dirac magnon material Cu3TeO6
Di Wang, Xiangyan Bo, Feng Tang +1
Recently topological aspects of magnon band structure have attracted much interest, and especially, the Dirac magnons in Cu3TeO6 have been observed experimentally. In this work, we…
Correlation Driven Topological Insulator-to-Weyl Semimetal Transition in Actinide System UNiSn
Vsevolod Ivanov, Xiangang Wan, Sergey Y. Savrasov
Although strong electronic correlations are known to be responsible for some highly unusual behaviors of solids such as, metal--insulator transitions, magnetism and even high--temp…
Spin-orbit coupling driven insulating state in hexagonal iridates Sr3MIrO6 (M = Sr, Na and Li)
Xing Ming, Xiangang Wan, Carmine Autieri +2
The spin-orbit coupling (SOC) interactions, electron correlation effects and Hund coupling cooperate and compete with each other, leading to novel properties, quantum phase and non…
Towards ideal topological materials: Comprehensive database searches using symmetry indicators
Feng Tang, Hoi Chun Po, Ashvin Vishwanath +1
Topological materials (TMs) showcase intriguing physical properties defying expectations based on conventional materials, and hold promise for the development of devices with new f…
Topological Materials Discovery By Large-order symmetry indicators
Feng Tang, Hoi Chun Po, Ashvin Vishwanath +1
Crystalline symmetries play an important role in the classification of band structures, and the rich variety of spatial symmetries in solids leads to various topological crystallin…
Efficient Topological Materials Discovery Using Symmetry Indicators
Feng Tang, Hoi Chun Po, Ashvin Vishwanath +1
Although the richness of spatial symmetries has led to a rapidly expanding inventory of possible topological crystalline (TC) phases of electrons, physical realizations have been s…
