Suppression and enhancement of bosonic stimulation by atomic interactions
Konstantinos Konstantinou, Yansheng Zhang, Paul H. C. Wong +7
The tendency of identical bosons to bunch, seen in the Hanbury Brown-Twiss effect and Bose-Einstein condensation, is a hallmark of quantum statistics. This bunching can enhance the…
Probing quantum many-body dynamics using subsystem Loschmidt echos
Simon Karch, Souvik Bandyopadhyay, Zheng-Hang Sun +9
The Loschmidt echo - the probability of a quantum many-body system to return to its initial state following a dynamical evolution - generally contains key information about a quant…
In situ imaging of the thermal de Broglie wavelength in an ultracold Bose gas
Jinggang Xiang, Enid Cruz-Colón, Candice C. Chua +4
We report the first in situ observation of density fluctuations on the scale of the thermal de Broglie wavelength in an ultracold gas of bosons. Bunching of Rb atoms in a qu…
A conveyor-belt magneto-optical trap of CaF
Scarlett S. Yu, Jiaqi You, Yicheng Bao +8
We report the experimental realization of a conveyor-belt magneto-optical trap for calcium monofluoride (CaF) molecules. The obtained highly-compressed cloud has a mean radius of 6…
