Kibble-Zurek Dynamics in a Trapped Ultracold Bose Gas
I-Kang Liu, Jacek Dziarmaga, Shih-Chuan Gou +2
The dynamical evolution of an inhomogeneous ultracold atomic gas quenched at different controllable rates through the Bose-Einstein condensation phase transition is studied numeric…

Che-Hsiu Hsueh, Chi-Ho Cheng, Tzyy-Leng Horng +1
Thermalization in an isolated oscillating Bose-Einstein condensate in a disordered trap is investigated. We show Shannon entropy in or representation is the eligible one to…
Dynamical Equilibration Across a Quenched Phase Transition in a Trapped Quantum Gas
I. -K. Liu, S. Donadello, G. Lamporesi +4
The formation of an equilibrium quantum state from an uncorrelated thermal one through the dynamical crossing of a phase transition is a central question of non-equilibrium many-bo…
Turbulence scaling laws across the superfluid to supersolid transition
C. -H. Hsueh, Y. -C. Tsai, T. -L. Horng +2
We investigate quantum turbulence in a two-dimensional trapped supersolid and demonstrate that both the wave and vortex turbulence involve triple rather than dual cascades, as in a…

Chi-Ho Cheng, S. -K. Yip
We consider the thermodynamic potential of an N component Fermi gas with a short range interaction obeying SU(N) symmetry. We analyze especially the part of that depends on…
Hidden long-range order in a spin-orbit coupled two-dimensional Bose gas
Shih-Wei Su, I-Kang Liu, Shih-Chuan Gou +3
A spin-orbit coupled two-dimensional (2D) Bose gas is shown to simultaneously possess quasi and true long-range order in the total and relative phase sectors, respectively. The tot…
Phase Separation and Dynamics of two-component Bose-Einstein condensates
Kean Loon Lee, Nils B. Jørgensen, I-Kang Liu +3
The miscibility of two interacting quantum systems is an important testing ground for the understanding of complex quantum systems. Two-component Bose-Einstein condensates enable t…

We explore a new way of producing the Rashba spin-orbit coupling (SOC) for ultracold atoms by using a two-component (spinor) atomic Bose-Einstein condensate (BEC) confined in a bil…
All-optical control of superradiance and matter waves using a dispersive cavity
Shih-Wei Su, Zhen-Kai Lu, Nina Rohringer +2
Cavity quantum electrodynamics (CQED) plays an elegant role of studying strong coupling between light and matter. However, a non-mechanical, direct and dynamical control of the use…
Unconventional Bose-Einstein Condensation in a System of Two-species Bosons in the -orbital Bands of a Bipartite Lattice
