Resonant-impurity scanning tunneling spectroscopy in altermagnets: dual Fano resonance and Landau-quantization-induced nodal spin contrast
Yuan Hong, Zhigang Wang, Zhen-Guo Fu +4
Using a Green's-function formalism, we study the spin-resolved local spectral function of a resonant impurity coupled to a two-dimensional % -wave altermagnetic substrate. It is…
Tunable Fano and Dicke effects in quantum transport of double quantum dots sandwiched between topological insulators
Yuan Hong, Zhen-Guo Fu, Zhou-Wei-Yu Chen +4
We study the quantum transport in double quantum dots (DQD) sandwiched between surfaces of topological insulator (TI) BiTe, which possess strong spin-orbit coupling (SO…
Chiral topological excitonic insulator in semiconductor quantum wells
Ningning Hao, Ping Zhang, Jian Li +3
We present a scheme to realize the chiral topological excitonic insulator in semiconductor heterostructures which can be experimentally fabricated with a coupled quantum well adjac…
Exciton condensation and fractional charge in a bilayer two-dimension electron gas adjacent to a superconductor film
Ningning Hao, Ping Zhang, Jian Li +2
We study the exciton condensate (EC) in a bilayer two-dimension-electron-gas (2DEG) adjacent to a type-II superconductor thin film with an array of pinned vortex lattices. By apply…
Fractional topological excitations and quantum phase transition in a bilayer 2DEG adjacent to a superconductor film
Ningning Hao, Wei Zhang, Zhigang Wang +2
We study a bilayer two-dimension-electron-gas (2DEG) adjacent to a type-II superconductor thin film with a pinned vortex lattice. We find that with increasing interlayer tunneling,…
Magnetization in two-dimensional electron gas in a perpendicular magnetic field: the roles of edge states and spin-orbit coupling
Zhigang Wang, Wei Zhang, Ping Zhang
We study the de Haas--van Alphen (dHvA) oscillations in the magnetization of a two-dimensional electron gas (2DEG) under the influence of the edge states and/or the Rashba spin-orb…
Topological edge states and quantum Hall effect in the Haldane model
Ningning Hao, Ping Zhang, Zhigang Wang +2
We study the topological edge states of the Haldane's graphene model with zigzag/armchair lattice edges. The Harper equation for solving the energies of the edge states is derived.…
