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…
Collective emission and selective radiance in atomic clouds and arrays coupled to a microring resonator
Deepak A. Suresh, Xinchao Zhou, Chen-Lung Hung +1
We theoretically investigate the collective dipole-dipole interactions in atoms coupled to a nanophotonic microring resonator. The atoms can interact with each other through light-…
Selective collective emission from a dense atomic ensemble coupled to a nanophotonic resonator
Xinchao Zhou, Deepak A. Suresh, F. Robicheaux +1
We experimentally and theoretically study collective emission of a dense atomic ensemble coupled to a single mode in a nanophotonic microring resonator. Because many cold atoms are…
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…
