Electric spin and valley Hall effects
W. Zeng
The electric Hall effect (EHE) is a newly identified Hall effect characterized by a perpendicular electric field inducing a transverse charge current in two-dimensional (2D) system…
Evanescent-mode-assisted Klein tunneling in dual-gated bilayer graphene
Yupeng Huang, W. Zeng
We theoretically investigate the electron tunneling in dual-gated bilayer graphene-based junctions. It is shown that a band gap is introduced by tuning the gate voltage, whic…
Observation of Embedded Topology in a Trivial Bulk via Projective Crystal Symmetry
Hau Tian Teo, Yang Long, Hong-yu Zou +6
Bulk-boundary correspondence is the foundational principle of topological physics, first established in the quantum Hall effect, where a -dimensional topologically nontrivial bu…
Tunneling spin Hall effect induced by unconventional -wave magnetism
W. Zeng
We propose a tunneling spin Hall effect in a normal metal/-wave magnet/superconductor junction. It is found that the Andreev reflection in the normal lead is spin-dependent and…
