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…
Observation of quantum-classical transition behavior of LGI in a dissipative quantum gas
Qinxuan Peng, Bolong Jiao, Hang Yu +4
The Leggett-Garg inequality (LGI) is a powerful tool for distinguishing between quantum and classical properties in studies of macroscopic systems. Applying the LGI to non-Hermitia…
