Graphyne as a second-order and real Chern topological insulator in two dimensions
Cong Chen, Weikang Wu, Zhi-Ming Yu +4
Higher-order topological phases and real topological phases are two emerging topics in topological states of matter, which have been attracting considerable research interest. Howe…
Universal Approach to Magnetic Second-Order Topological Insulator
Cong Chen, Zhida Song, Jian-Zhou Zhao +4
We propose a universal practical approach to realize magnetic second-order topological insulator (SOTI) materials, based on properly breaking the time reversal symmetry in conventi…
Large transverse thermoelectric figure of merit in a Dirac semimetal
Junsen Xiang, Sile Hu, Meng Lyu +6
Thermoelectric (TE) conversion in conducting materials is of eminent importance for providing renewable energy and solid-state cooling. Although traditionally, the Seebeck effect p…
Weyl-loop half metal in Li(FeO)
Cong Chen, Zhi-Ming Yu, Si Li +3
Nodal-line metals and semimetals, as interesting topological states of matter, have been mostly studied in nonmagnetic materials. Here, based on first-principles calculations and s…
From Multiple Nodal Chain to Dirac/Weyl Semimetal and Topological Insulator in Ternary Hexagonal Materials
Cong Chen, Zefeng Su, Xiaoming Zhang +2
Dirac semimetal (DSM) hosts four-fold degenerate isolated band-crossing points with linear dispersion, around which the quasiparticles resemble the relativistic Dirac Fermions. It…
Hybrid Dirac Semimetal in CaAgBi Materials Family
Cong Chen, Shan-Shan Wang, Lei Liu +4
Based on their formation mechanisms, Dirac points in three-dimensional systems can be classified as accidental or essential. The former can be further distinguished into type-I and…
