Topological states and topological phase transition in Cu2SnS3 and Cu2SnSe3
Liqin Zhou, Yuting Qian, Changming Yue +4
Based on the first-principles calculations within local density approximation and model analysis, we propose that the iso-structural compounds Cu2SnS3 and Cu2SnSe3 are both the sim…
Topological Crystalline Insulators with Rotation Anomaly
Tan Zhang, Changming Yue, Tiantian Zhang +5
Based on first-principles calculations and symmetry-based indicator analysis, we find a class of topological crystalline insulators (TCIs) with rotation anomaly in a family o…
Topological Thermoelectricity in Metals
Sobhit Singh, QuanSheng Wu, Changming Yue +2
Recently published discoveries of acoustic and optical mode inversion in the phonon spectrum of certain metals became the first realistic example of non-interacting topological bos…
Predicting Dirac semimetals based on Sodium Ternary Compounds
Bo Peng, Changming Yue, Hao Zhang +2
Predicting a new Dirac semimetal (DSM), as well as other topological materials, is quite challenging, since the relationship between crystal structure, composing atoms and the band…
Topological Dirac Nodal-net Fermions in AlB-type TiB and ZrB
Xing Feng, Changming Yue, Zhida Song +2
Based on first-principles calculations and effective model analysis, a Dirac nodal-net semimetal state is recognized in AlB-type TiB and ZrB when spin-orbit coupling (S…
