Quantum dynamics with spatiotemporal control of interactions in a stable Bose-Einstein condensate
Logan W. Clark, Li-Chung Ha, Chen-Yu Xu +1
Optical control of atomic interactions in a quantum gas is a long-sought goal of cold atom research. Previous experiments have been hindered by short lifetimes and parasitic deform…
Universal Loss Dynamics in a Unitary Bose Gas
Ulrich Eismann, Lev Khaykovich, Sébastien Laurent +8
The low temperature unitary Bose gas is a fundamental paradigm in few-body and many-body physics, attracting wide theoretical and experimental interest. Here we first present a the…
Roton-Maxon Excitation Spectrum of Bose Condensates in a Shaken Optical Lattice
Li-Chung Ha, Logan W. Clark, Colin V. Parker +2
We present experimental evidence showing that an interacting Bose condensate in a shaken optical lattice develops a roton-maxon excitation spectrum, a feature normally associated w…
Anomalous thermoelectric transport in two-dimensional Bose gas
Eric L. Hazlett, Li-Chung Ha, Cheng Chin
In condensed matter physics, transport measurements are essential not only for the characterization of materials, but also to discern between quantum phases and identify new ones.…
In situ observation of strongly interacting ferromagnetic domains in a shaken optical lattice
Colin V. Parker, Li-Chung Ha, Cheng Chin
Solid state systems derive their richness from the interplay between interparticle interactions and novel band structures that deviate from those of free particles. Strongly intera…
Strongly Interacting Two-Dimensional Bose Gases
Li-Chung Ha, Chen-Lung Hung, Xibo Zhang +3
We prepare and study strongly interacting two-dimensional Bose gases in the superfluid, the classical Berezinskii-Kosterlitz-Thouless (BKT) transition, and the vacuum-to-superfluid…
Extracting density-density correlations from in situ images of atomic quantum gases
Chen-Lung Hung, Xibo Zhang, Li-Chung Ha +3
We present a complete recipe to extract the density-density correlations and the static structure factor of a two-dimensional (2D) atomic quantum gas from in situ imaging. Using im…
