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…
Observation of self-patterned defect formation in atomic superfluids -- from ring dark solitons to vortex dipole necklaces
Hikaru Tamura, Cheng-An Chen, Chen-Lung Hung
Unveiling nonequilibrium dynamics of solitonic and topological defect structures in a multidimensional nonlinear medium is a current frontier across diverse fields. One of the quin…
Observation of scale invariance in two-dimensional matter-wave Townes solitons
Cheng-An Chen, Chen-Lung Hung
We report near-deterministic generation of two-dimensional (2D) matter-wave Townes solitons, and a precision test on scale invariance in attractive 2D Boses gases. We induce a shap…
Observation of quasiparticle pair-production and quantum entanglement in atomic quantum gases quenched to an attractive interaction
Cheng-An Chen, Sergei Khlebnikov, Chen-Lung Hung
We report observation of quasiparticle pair-production and characterize quantum entanglement created by a modulational instability in an atomic superfluid. By quenching the atomic…
Observation of universal quench dynamics and Townes soliton formation from modulational instability in two-dimensional Bose gases
Cheng-An Chen, Chen-Lung Hung
We experimentally study universal nonequilibrium dynamics of two-dimensional atomic Bose gases quenched from repulsive to attractive interactions. We observe the manifestation of m…
