Quantum transport in a one-dimensional quasicrystal with mobility edges

Yan Xing, Lu Qi, Xuedong Zhao +4

Quantum transport in a one-dimensional (1D) quasiperiodic lattice with mobility edges is explored. We first investigate the adiabatic pumping between left and right edge modes by r…

Topological phase induced by distinguishing parameter regimes in cavity optomechanical system with multiple mechanical resonators

Lu Qi, Yan Xing, Shutian Liu +2

We propose two kinds of distinguishing parameter regimes to induce topological Su-Schrieffer-Heeger (SSH) phase in a one dimensional (1D) multi-resonator cavity optomechanical syst…

Topological and nontopological edge states induced by qubit-assisted coupling potentials

Lu Qi, Yan Xing, Guo-Li Wang +2

In the usual Su-Schrieffer-Heeger (SSH) chain, the topology of the energy spectrum is divided into two categories in different parameter regions. Here we study the topological and…

Simulating Z_2 topological insulators via a one-dimensional cavity optomechanical cells array

Lu Qi, Yan Xing, Hong-Fu Wang +2

We propose a novel scheme to simulate Z_2 topological insulators via one-dimensional (1D) cavity optomechanical cells array. The direct mapping between 1D cavity optomechanical cel…

Spontaneous PT symmetry breaking in non-Hermitian coupled cavities array

Yan Xing, Lu Qi, Ji Cao +5

We study the effects of the position of the passive and active cavities on the spontaneous parity-time (PT) symmetry breaking behavior in non-Hermitian coupled cavities array model…
