Breathing Modes as a Probe of Energy Fluctuations in a Unitary Fermi Gas
Shi-Guo Peng, Jing Min, Kaijun Jiang
Directly accessing energy fluctuations in interacting quantum many-body systems remains a long-standing challenge, especially far from equilibrium. Here we show that in scale-invar…
Energy Dynamics of a Nonequilibrium Unitary Fermi Gas
Xiangchuan Yan, Jing Min, Dali Sun +4
We investigate the energy dynamics of a unitary Fermi gas driven away from equilibrium. The energy is injected into the system by periodically modulating the trapping potential of…
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…
