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…
Effect of photonic band gap on entanglement dynamics of qubits
Jing-Nuo Wu, Wen-Feng Hsieh, Szu-Cheng Cheng
We study how the environment of photonic band gap (PBG) materials affects entanglement dynamics of qubits. Entanglement between the single qubit and the PBG environment is investig…
Dynamics of relaxation, decoherence and entropy of a qubit in anisotropic photonic crystals
Jing-Nuo Wu, Hung-Kuang Chen, Wen-Feng Hsieh +1
We study the quantum dynamics of relaxation, decoherence and entropy of a qubit embedded in an anisotropic photonic crystal (PhC) through fractional calculus. These quantum measure…
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…
