Attractive Multidimensional Condensates--Experiments
Hikaru Tamura, Chen-Lung Hung
Experiments on attractive Bose-Einstein condensates (BECs) have unlocked many intriguing out-of-equilibrium dynamics through the interplay between matter-wave dispersion and nonlin…
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…
Observation of self-oscillating supersonic flow across an acoustic horizon in two dimensions
Hikaru Tamura, Sergei Khlebnikov, Cheng-An Chen +1
Understanding the dynamics and stability of transonic flows in quantum fluids, especially for those beyond one spatial dimension, is an outstanding challenge, with applications ran…
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…
