Phase-locking matter-wave interferometer of vortex states
Lingran Kong, Tianyou Gao, Longzhi Nie +5
Matter-wave interferometer of ultracold atoms with different linear momenta has been extensively studied in theory and experiment. The vortex matter-wave interferometer with differ…
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,…
Optimizing the optical imaging system by \emph{in-situ} imaging the plugged hole in the ultracold atoms
Tianyou Gao, Dongfang Zhang, Lingran Kong +2
Optical absorption imaging has become a common technique for detecting the density distribution of ultracold atoms. The defocus effect generally produces artificial spatial structu…
