Complex semiclassical theory for non-Hermitian quantum systems
Guang Yang, Yongkang Li, Yongxu Fu +2
Non-Hermitian quantum systems exhibit fascinating characteristics such as non-Hermitian topological phenomena and skin effect, yet their studies are limited by the intrinsic diffic…
Oblique and asymmetric Klein tunneling across smooth NP junctions or NPN junctions in 8-Pmmn borophene
Zhan Kong, Jian Li, Yi Zhang +2
The tunneling of electrons and holes in quantum structures plays a crucial role in studying the transport properties of materials and the related devices. 8-Pmmn borophene is a new…
Quantum-limit Hall effect with large carrier density in topological semimetals
Guang Yang, Yi Zhang
The quantum-limit Hall effect at that hosts a variety of exotic quantum phenomena requires demanding strong magnetic field and low carrier density . We p…
Cyclotron orbit knot and tunable-field quantum Hall effect
Yi Zhang
From a semiclassical perspective, the Bohr-Sommerfeld quantization of the closed cyclotron orbits for charged particles such as electrons in an external magnetic field gives rise t…
Quantum oscillations from generic surface Fermi arcs and bulk chiral modes in Weyl semimetals
Yi Zhang, Daniel Bulmash, Pavan Hosur +2
We re-examine the question of quantum oscillations from surface Fermi arcs and chiral modes in Weyl semimetals. By introducing two tools - semiclassical phase-space quantization an…
The almost mobility edge in the almost Mathieu equation
Yi Zhang, Daniel Bulmash, Akash V. Maharaj +2
Harper's equation (aka the "almost Mathieu" equation) famously describes the quantum dynamics of an electron on a one dimensional lattice in the presence of an incommensurate poten…
