Computation and data driven discovery of topological phononic materials
Jiangxu Li, Jiaxi Liu, Stanley A. Baronett +4
The discovery of topological quantum states marks a new chapter in both condensed matter physics and materials sciences. By analogy to spin electronic system, topological concepts…
Underlying topological Dirac nodal line mechanism of anomalously large electron-phonon coupling strength on Be (0001) surface
Ronghan Li, Jiangxu Li, Lei Wang +4
Beryllium was recently discovered to harbor a Dirac nodal line (DNL) in its bulk phase and the DNL-induced non-trivial drumhead-like surface states (DNSSs) on its (0001) surface, r…
Topological Weyl-like Phonons and Nodal Line Phonons in Graphene
Jiangxu Li, Lei Wang, Jiaxi Liu +3
By means of first-principles calculations and modeling analysis, we have predicted that the traditional 2D-graphene hosts the topological phononic Weyl-like points (PWs) and phonon…
Rashba spin splitting of L-gap surface states on Ag(111) and Cu(111)
Koichiro Yaji, Ayumi Harasawa, Kenta Kuroda +4
Spin-resolved band structures of L-gap surface states on Ag(111) and Cu(111) are investigated by spin- and angle-resolved photoelectron spectroscopy (SARPES) with a vacuum-ultra-vi…
