Expansion dynamics of a spherical Bose-Einstein condensate
Ruizong Li, Tianyou Gao, Dongfang Zhang +5
We experimentally and theoretically observe the expansion behaviors of a spherical Bose-Einstein condensate. A rubidium condensate is produced in an isotropic optical dipole trap w…
Observation of quantum phase transition in spin-orbital-angular-momentum coupled Bose-Einstein condensate
Dongfang Zhang, Tianyou Gao, Peng Zou +8
Orbital angular momentum (OAM) of light represents a fundamental optical freedom that can be exploited to manipulate quantum state of atoms. In particular, it can be used to realiz…
Observation of phonon parametric down-conversion in a spherical Bose-Einstein condensate
Tianyou Gao, Jian-Song Pan, Dongfang Zhang +8
We report the observation of parametric down-conversion of phonons in a spherical Bose-Einstein condensate. The spherical symmetry, which is crucial for observing this phenomenon,…
Phase separation and hidden vortices induced by spin-orbit coupling in spin-1 Bose-Einstein condensates
Ji Li, Yan-Mei Yu, Kai-Jun Jiang +1
We investigate phase separation and hidden vortices in spin-orbit coupled ferromagnetic BoseEinstein condensates with rotation and Rabi coupling. The hidden vortices are invisible…
