Observation of the nonlinear Hall effect under time reversal symmetric conditions
Qiong Ma, Su-Yang Xu, Huitao Shen +18
The electrical Hall effect is the production of a transverse voltage under an out-of-plane magnetic field. Historically, studies of the Hall effect have led to major breakthroughs…
Aspects of symmetry and topology in the charge density wave phase of 1T-TiSe2
Shin-Ming Huang, Su-Yang Xu, Bahadur Singh +5
The charge density wave (CDW) in 1T-TiSe2 accompanied by the periodic lattice distortion has a nontrivial symmetry configuration. The symmetry is important as an indication of the…
Topological crystalline insulator states in the CaAs family
Xiaoting Zhou, Chuang-Han Hsu, Tay-Rong Chang +9
Topological crystalline insulators (TCI) are insulating electronic phases of matter with nontrivial topology originating from crystalline symmetries. Recent theoretical advances ha…
Room-temperature nanoseconds spin relaxation in WTe2 and MoTe2 thin films
Qisheng Wang, Jie Li, Jean Besbas +11
The Weyl semimetal WTe2 and MoTe2 show great potential in generating large spin currents since they possess topologically-protected spin-polarized states and can carry a very large…
