Superfluid density and collective modes of fermion superfluid in dice lattice
Yu-Rong Wu, Xiao-Fei Zhang, Chao-Fei Liu +2
The superfluid properties of attractive Hubbard model in dice lattice are investigated. It is found that three superfluid order parameters increase as the interaction increases. Wh…
Degenerate Rabi spectroscopy of the Floquet engineered optical lattice clock
Wei-Xin Liu, Xiao-Tong Lu, Ting Li +4
Simulating physics with large SU(N) symmetry is one of the unique advantages of Alkaline-earth atoms.Introducing periodical driving modes to the system may provide more rich SU(N)…
Floquet engineering Hz-Level Rabi Spectra in Shallow Optical Lattice Clock
Mo-Juan Yin, Tao Wang, Xiao-Tong Lu +4
Quantum metrology with ultra-high precision usually requires atoms prepared in an ultra-stable environment with well-defined quantum states. Thus, in optical lattice clock systems…
Doubly Modulated Optical Lattice Clock Interference and Topology
Xiao-Tong Lu, Tao Wang, Ting Li +5
The quantum system under periodical modulation is the simplest path to understand the quantum non-equilibrium system, because it can be well described by the effective static Floqu…
Rabi Spectroscopy and Sensitivity of a Floquet Engineered Optical Lattice Clock
Mo-Juan Yin, Tao Wang, Xiao-Tong Lu +6
We periodically modulate the lattice trapping potential of a Sr optical clock to Floquet engineer the clock transition. In the context of atomic gases in lattices, Floquet e…
Gauge-potential-induced rotation of spin-orbit-coupled Bose-Einstein condensates
Jingjing Jin, Wei Han, Suying Zhang
We demonstrate that a spin-orbit-coupled Bose-Einstein condensate can be effectively rotated by adding a real magnetic field to inputting gauge angular momentum, which is distinctl…
