Suppression of Bloch Oscillations and Nonreciprocal Landau-Zener Tunneling in Bose-Einstein Quantum Droplets
Szu-Cheng Cheng, Yu-Wen Wang, Wen-Feng Hsieh +2
We investigate the nonlinear Bloch dynamics and Landau-Zener (LZ) tunneling of quantum droplets in optical lattices. We show that the Lee-Huang-Yang (LHY) correction not only stabi…
Phase diagram of microcavity polariton condensates with a harmonic potential trap
Ting-Wei Chen, Min g-Dar Wei, Szu-Cheng Cheng +1
We theoretically explore the phase transition in inhomogeneous exciton-polariton condensates with variable pumping conditions. Through Bogoliubov excitations to the radial-symmetri…
Stability and Excitations of Spontaneous Vortices in Homogeneous Polariton Condensates
Ting-Wei Chen, Szu-Cheng Cheng, Wen-Feng Hsieh
We study the dynamics of spontaneously formed vortices in homogeneous microcavity-polariton condensates (MPCs). We find that vortices are stable and appear spontaneously without st…
Collective Excitations, Nambu-Goldstone Modes and Instability of Inhomogeneous Polariton Condensates
Ting-Wei Chen, Szu-Cheng Cheng, Wen-Feng Hsieh
We study non-equilibrium microcavity-polariton condensates (MPCs) in a harmonic potential trap theoretically. We calculate and analyze the steady state, collective-excitation modes…
