Persistent breather and dynamical symmetry in a unitary Fermi gas
Dali Sun, Jing Min, Xiangchuan Yan +8
SO(2,1) dynamical symmetry makes a remarkable prediction that the breathing oscillation of a scale invariant quantum gas in an isotropic harmonic trap is isentropic and can persist…

Macroscopic superposition of vortex states in a matter wave
Lingran Kong, Tianyou Gao, Shi-Guo Peng +7
Generating the vortex-state superposition in a matter wave is demanded in many quantum processes such as quantum memory and quantum metrology. Here we report the experimental gener…
