Exploring control of the emergent exciton insulator state in 1T-TiSe monolayer by state-of-the-art theory models
Hong Tang, Li Yin, Gábor I. Csonka +1
The layered transition metal dichalcogenide 1T-TiSe is of great research interest, having intriguing properties of charge density waves (CDW) and superconductivity under doping…
Inside the Working Mechanism of Meta-generalized Gradient Density Functional Approximations: The Example of Quantum Spin-Hall Insulator 1T`-WTe2
Li Yin, Hong Tang, Adrienn Ruzsinszky
Quantum spin Hall (QSH) insulators have attracted intensive experimental and theoretical studies due to their beneficial applications in spintronic devices. Density functional theo…
Multiple Incommensurate Magnetic States in the Kagome Antiferromagnet Na2Mn3Cl8
Joseph A. M. Paddison, Li Yin, Keith M. Taddei +4
The kagome lattice can host exotic magnetic phases arising from frustrated and competing magnetic interactions. However, relatively few insulating kagome materials exhibit incommen…
Bending effects and optical properties of WSe2 nanoribbons of topological phase
Hong Tang, Jason M. Breslin, Li Yin +1
A WSe2 monolayer of 1T' phase is a large band gap quantum spin Hall insulator, supporting dissipationless charge and spin transports through the topologically protected edge states…
