Direct observation of long-range many-body coherence in quasi-one-dimensional attractive Bose gases
Hikaru Tamura, Sambit Banerjee, Rongjie Li +3
Macroscopic coherence is an important feature of quantum many-body systems exhibiting collective behaviors, with examples ranging from atomic Bose-Einstein condensates, and quantum…

Collapse of a quantum vortex in an attractive two-dimensional Bose gas
Sambit Banerjee, Kai Zhou, Shiva Kant Tiwari +6
We experimentally and numerically study the collapse dynamics of a quantum vortex in a two-dimensional atomic superfluid following a fast interaction ramp from repulsion to attract…
