Coexistence of topological Anderson insulator and multifractal critical phase in a non-Hermitian quasicrystal
Qi-Bo Zeng, Rong Lü
The interplay of topology, disorder, and non-Hermiticity gives rise to phenomena beyond the conventional classification of quantum phases. We propose a one-dimensional non-Hermitia…
Topological superconducting phase in a non-Hermitian Kitaev chain with staggered pairing imbalance
Xiao-Jue Zhang, Rong Lü, Qi-Bo Zeng
We introduce a one-dimensional non-Hermitian Kitaev chain with staggered imbalance in the -wave superconducting pairing. By tuning the chemical potential and the pairing imbalan…
Dissolution of the non-Hermitian skin effect in one-dimensional lattices with linearly varying nonreciprocal hopping
Bo Hou, Han Xiao, Rong Lü +1
We study the one-dimensional non-Hermitian lattices with linearly varying nonreciprocal hopping, where the non-Hermitian skin effect (NHSE) is found to be dissolved gradually as th…
Real spectra, Anderson localization, and topological phases in one-dimensional quasireciprocal systems
Qi-Bo Zeng, Rong Lü
We introduce the one-dimensional quasireciprocal lattices where the forward hopping amplitudes between nearest neighboring sites are chosen to be a random permutat…
Quench dynamics in the Aubry-André-Harper model with \textit{p}-wave superconductivity
Qi-Bo Zeng, Shu Chen, Rong Lü
The Anderson localization phase transition in the Aubry-André-Harper (AAH) model with \textit{p}-wave superconducting (SC) pairing is numerically investigated by suddenly changing…
Transport through a quantum dot coupled to two Majorana bound states
Qi-Bo Zeng, Shu Chen, L. You +1
We investigate electron transport inside a ring system composed of a quantum dot (QD) coupled to two Majorana bound states confined at the ends of a one-dimensional topological sup…
Dynamical Generation of Topological Magnetic Lattices for Ultracold Atoms
Jinlong Yu, Zhi-Fang Xu, Rong Lü +1
We propose a scheme to dynamically synthesize a space-periodic effective magnetic field for neutral atoms by time-periodic magnetic field pulses. When atomic spin adiabatically fol…
Spin tunneling properties in mesoscopic magnets: effects of a magnetic field
Rong Lu, Hui Pan, Jia-Lin Zhu +1
The tunneling of a giant spin at excited levels is studied theoretically in mesoscopic magnets with a magnetic field at an arbitrary angle in the easy plane. Different structures o…
Resonant quantum coherence of magnetization at excited states in nanospin systems with different crystal symmetries
Jia-Lin Zhu, Rong Lu, Su-Pen Kou +2
The quantum interference effects induced by the Wess-Zumino term, or Berry phase are studied theoretically in resonant quantum coherence of magnetization vector between degenerate…
