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…
Dissipation-induced topological phase transition and periodic-driving-induced photonic topological state transfer in a small optomechanical lattice
Lu Qi, Guo-Li Wang, Shutian Liu +2
We propose a scheme to investigate the topological phase transition and the topological state transfer based on the small optomechanical lattice under the realistic parameters regi…
Engineering of topological state transfer and topological beam splitter in an even-size Su-Schrieffer-Heeger chain
Lu Qi, Guo-Li Wang, Shutian Liu +2
The usual Su-Schrieffer-Heeger model with an even number of lattice sites possesses two degenerate zero energy modes. The degeneracy of the zero energy modes leads to the mixing be…
Robust interface-state laser in non-Hermitian micro-resonator arrays
Lu Qi, Guo-Li Wang, Shutian Liu +2
We propose a scheme to achieve the analogous interface-state laser by dint of the interface between the two intermediate-resonator-coupled non-Hermitian resonator chains. We find t…
Controllable double quantum state transfers by one topological channel in a frequency-modulated optomechanical array
Lu Qi, Shutian Liu, Shou Zhang +1
We propose a scheme to achieve the quantum state transfer via the topological protected edge channel based on a one dimensional frequency-modulated optomechanical array. We find th…
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…
