Observation of Vinen turbulence during far-from-equilibrium Bose-Einstein condensation
Sebastian J. Morris, Martin Gazo, Simon M. Fischer +5
Relaxation of far-from-equilibrium quantum fluids, intimately related to the emergence of long-range order, is theoretically associated with the decay of a turbulent isotropic tang…
Fate of an impurity strongly interacting with a thermal Bose gas
Jiří Etrych, Sebastian J. Morris, Simon M. Fischer +7
We spectroscopically study mobile impurities immersed in a homogeneous bosonic bath (a box-trapped Bose gas), varying the bath temperature and the strength of impurity-bath interac…
Scaling Laws Governing the Collapse of a Bose-Einstein Condensate
Sebastian J. Morris, Christopher J. Ho, Simon M. Fischer +4
We study the collapse of an attractive Bose-Einstein condensate, where an unstable system evolves towards a singularity, by numerically solving the underlying cubic-quintic nonline…
Joule expansion of a quantum gas
Christopher J. Ho, Simon M. Fischer, Gevorg Martirosyan +4
We revisit the classic Joule-expansion experiments, now with a quantum-degenerate atomic Bose gas. In contrast to the classical-gas experiments, where no temperature change was mea…
A universal speed limit for spreading of coherence
Gevorg Martirosyan, Martin Gazo, Jiří Etrych +5
Discoveries of fundamental limits for the rates of physical processes, from the speed of light to the Lieb-Robinson bound for information propagation, often lead to breakthroughs i…
Universal quantum dynamics of Bose polarons
Jiří Etrych, Gevorg Martirosyan, Alec Cao +3
Predicting the emergent properties of impurities immersed in a quantum bath is a fundamental challenge that can defy quasiparticle treatments. Here, we measure the spectral propert…
Energy-space random walk in a driven disordered Bose gas
Yansheng Zhang, Gevorg Martirosyan, Christopher J. Ho +3
Motivated by the experimental observation [1] that driving a non-interacting Bose gas in a 3D box with weak disorder leads to power-law energy growth, with $η=0.46(…
