Orbital-Dependent Dimensional Crossover of a -Wave Feshbach Resonance
Hang Yu, Liao Sun, Shaokun Liu +3
We report the observation of a dimensional crossover of a -wave Feshbach resonance in an ultracold, spin-polarized Li Fermi gas confined by a one-dimensional optical lattice…
Accelerating evaporative cooling of a strongly interacting Fermi gas by tilting the optical trap with a magnetic field gradient
Bolong Jiao, Shuai Peng, Qinxuan Peng +4
We present a rapid evaporative cooling scheme for a strongly interacting Fermi gas in an optical dipole trap. The method uses a magnetic-field-gradient--induced t…
Orbital-resolved three-body recombination across a p-wave Feshbach resonance in ultracold Li
Shaokun Liu, Zhekang Xu, Shuai Peng +4
We report precision, orbital-resolved measurements of three-body recombination near the 159~G -wave Feshbach resonance in an ultracold gas of Li atoms prepared in their lo…
Shot-Noise-Limited Laser Frequency Stabilization Using a High-Resolution Wavelength Meter
Mengde Gan, Haoyi Zhang, Xiaodong Tan +2
We present a compact laser frequency stabilization method by locking a 556 nm laser to a high-precision wavelength meter. Unlike traditional schemes that rely on optical cavities o…
Precision Measurement of Spin-Dependent Dipolar Splitting in Li p-Wave Feshbach Resonances
Shuai Peng, Sijia Peng, Lijun Ren +4
The magnetic dipolar splitting of a p-wave Feshbach resonance is governed by the spin-orbital configuration of the valence electrons in the triplet molecular state. We perform high…
Efficient shortcuts-to-adiabaticity for loading an ultracold Fermi gas into higher orbital bands of one-dimensional optical lattice
Hang Yu, Haoyi Zhang, Bolong Jiao +4
We propose an experimental scheme to load ultracold Fermi gases from the ground orbital band of a one-dimensional optical lattice into the first excited orbital band. Unlike the na…
