Reproduction of the charge density wave phase diagram in - exposes its excitonic character

Chuan Chen, Bahadur Singh, Hsin Lin +1

Recent experiments suggest that excitonic degrees of freedom play an important role in precipitating the charge density wave (CDW) transition in -. Through sys…

Topological Hopf and chain link semimetal states and their application to Co2MnGa (Theory and Materials Prediction)

Guoqing Chang, Su-Yang Xu, Xiaoting Zhou +9

Topological semimetals can be classified by the connectivity and dimensionality of the band cross- ing in momentum space. The band crossings of a Dirac, Weyl, or an unconventional…

Observation of Effective Pseudospin Scattering in ZrSiS

Michael S. Lodge, Guoqing Chang, Cheng-Yi Huang +10

3D Dirac semimetals are an emerging class of materials that possess topological electronic states with a Dirac dispersion in their bulk. In nodal-line Dirac semimetals, the conduct…

Saddle-like topological surface states on the TT'X family of compounds (T, T' = Transition metal, X= Si, Ge)

Bahadur Singh, Xiaoting Zhou, Hsin Lin +1

Topological nodal-line semimetals are exotic conductors that host symmetry-protected conducting nodal-lines in their bulk electronic spectrum and nontrivial drumhead states on the…

Stable charge density wave phase in a 1T-TiSe monolayer

Bahadur Singh, Chuang-Han Hsu, Wei-Feng Tsai +2

Charge density wave (CDW) phases are symmetry-reduced states of matter in which a periodic modulation of the electronic charge frequently leads to drastic changes of the electronic…
