Universal Scaling Laws in the Dynamics of a Homogeneous Unitary Bose Gas
Universal Scaling Laws in the Dynamics of a Homogeneous Unitary Bose Gas
We study the dynamics of an initially degenerate homogeneous Bose gas after an interaction quench to the unitary regime at a magnetic Feshbach resonance. As the cloud decays and heats, it exhibits a crossover from degenerate- to thermal-gas behaviour, both of which are characterised by universal scaling laws linking the …
