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…
