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…

Geometry-induced wavefunction collapse
Li-Li Ye, Chen-Di Han, Liang Huang +1
When a quantum particle moves in a curved space, a geometric potential can arise. In spite of a long history of extensive theoretical studies, to experimentally observe the geometr…

Deep-learning design of graphene metasurfaces for quantum control and Dirac electron holography
Chen-Di Han, Li-Li Ye, Zin Lin +2
Metasurfaces are sub-wavelength patterned layers for controlling waves in physical systems. In optics, meta-surfaces are created by materials with different dielectric constants an…
