Flat-Band Generation in InAs/GaSb Quantum Wells through Vertically Engineered Heterostructures
Zachery A. Enderson, Jiyuan Fang, Wei-Chen Wang +8
Quantum materials constitute a novel category of substances wherein quantum effects and electron-electron (e-e) interactions give rise to unforeseen phenomena on a macroscopic scal…
Applied-field magnetic structure and spectroscopy shifts of the effective spin-, -like magnet LiCoCl
Zachary W. Riedel, Mykhaylo Ozerov, Stuart Calder +1
Insulators containing chains of magnetic transition metal cations provide platforms for probing spin- dynamics and quantum critical behavior. LiCoCl contains e…
Linear scaling relation between two-dimensional massless Dirac fermion Fermi velocity and Fe-As bond length in iron arsenide superconductor systems
Chengpu Lv, Jianzhou Zhao, Yueshan Xu +6
Two-dimensional (2D) massless Dirac fermions (MDF), which represent a type of quasi-particles with linear energy-momentum dispersions only in 2D momentum space, provide a fertile g…
Spectral analysis of the magneto-optical response in valley polarized PbSnSe
Xiaoqi Ding, Jiashu Wang, Mykhaylo Ozerov +7
Since the last century, considerable efforts have been devoted to the study of valley-degenerate narrow gap semiconductors, such as the PbSnSe alloy. This material poss…
Unveiling three types of fermions in a nodal ring topological semimetal through magneto-optical transitions
Jiwon Jeon, Taehyeok Kim, Jiho Jang +5
We investigate the quasiparticles of a single nodal ring semimetal SrAs through axis-resolved magneto-optical measurements. We observe three types of Landau levels scaling as $…
