Spin-dependent edge states in two-dimensional Dirac materials with a flat band
Li-Li Ye, Chen-Di Han, Ying-Cheng Lai
The phenomenon of spin-dependent quantum scattering in two-dimensional (2D) pseudospin-1/2 Dirac materials leading to a relativistic quantum chimera was recently uncovered. We inve…
Generating extreme quantum scattering in graphene with machine learning
Chen-Di Han, Ying-Cheng Lai
Graphene quantum dots provide a platform for manipulating electron behaviors in two-dimensional (2D) Dirac materials. Most previous works were of the "forward" type in that the obj…
Optical response of two-dimensional Dirac materials with a flat band
Chen-Di Han, Ying-Cheng Lai
Two-dimensional Dirac materials with a flat band have been demonstrated to possess a plethora of unusual electronic properties, but the optical properties of these materials are le…
Chaos based Berry phase detector
Cheng-Zhen Wang, Chen-Di Han, Hong-Ya Xu +1
The geometric or Berry phase, a characteristic of quasiparticles, is fundamental to the underlying quantum materials. The discoveries of new materials at a rapid pace nowadays call…
Decay of semiclassical massless Dirac fermions from integrable and chaotic cavities
Chen-Di Han, Cheng-Zhen Wang, Hong-Ya Xu +2
Conventional microlasing of electromagnetic waves requires (1) a high cavity and (2) a mechanism for directional emission. Previous theoretical and experimental work demonstrat…
