The non-Hermitian geometrical property of 1D Lieb lattice under Majorana's stellar representation
Xingran Xu, Haodi Liu, Zhidong Zhang +1
The topological properties of non-Hermitian Hamiltonian is a hot topic, and the theoretical studies along this research line are usually based on the two-level non-Hermitian Hamilt…
Nonequilibrium Landau-Zener Tunneling in Exciton-Polariton Condensates
Xingran Xu, Zhidong Zhang, Zhaoxin Liang
For a coherent quantum mechanical two-level system driven with a linearly time-dependent detuning, the Landau-Zener model has served over decades as a textbook model of quantum dyn…
Dark-bright solitons in spinor polariton condensates under nonresonant pumping
Xingran Xu, Lei Chen, Zhidong Zhang +1
Adopting a mean-field Gross-Pitaevskii description for a spinor polariton Bose-Einstein condensates under non-resonant pumping, we investigate the static and dynamical properties o…
Spinor polariton condensates under nonresonant pumping: Steady states and elementary excitations
Xingran Xu, Ying Hu, Zhidong Zhang +1
We theoretically investigate a spinor polariton condensate under nonresonant pumping, based on driven-dissipative Gross-Pitaevskii equations coupled to the rate equation of a spin-…
