Weyl Ferroelectric Semimetal
Ronghan Li, Yuanfeng Xu, Jianggang He +7
The recent discoveries of ferroelectric metal and Weyl semimetal (WSM) have stimulated a natural question: whether these two exotic states of matter can coexist in a single materia…
Topologically entangled Rashba-split Shockley states on the surface of grey arsenic
Peng Zhang, J. -Z. Ma, Y. Ishida +13
We discover a pair of spin-polarized surface bands on the (111) face of grey arsenic by using angle-resolved photoemission spectroscopy (ARPES). In the occupied side, the pair rese…
Electron and hole doping in the relativistic Mott insulator SrIrO: a first-principles study using band unfolding technique
Peitao Liu, Michele Reticcioli, Bongjae Kim +5
We study the effects of dilute La and Rh doping on the electronic structure of the relativistic Mott insulator SrIrO using fully relativistic and magnetically non-collinear…
Dirac node lines in pure alkali earth metals
Ronghan Li, Xiyue Cheng, Hui Ma +5
Beryllium is a simple alkali earth metal, but has been the target of intensive studies for decades because of its unusual electron behaviors at surfaces. Puzzling aspects include (…
