Weak wave turbulence as a precursor to universal coarsening in a homogeneous Bose gas
Simon M. Fischer, Martin Gazo, Sebastian J. Morris +6
Relaxation and condensation of an isolated low-energy Bose gas provide an ideal setting for the study of the universal features of far-from-equilibrium many-body dynamics and the e…
An Equation of State for Turbulence in the Gross-Pitaevskii model
Gevorg Martirosyan, Kazuya Fujimoto, Nir Navon
We report the numerical observation of a far-from-equilibrium equation of state (EOS) in the Gross-Pitaevskii model. We first show that the momentum distribution of the turbulent c…
A universal speed limit for spreading of coherence
Gevorg Martirosyan, Martin Gazo, JiÅÃ 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…
Fate of an impurity strongly interacting with a thermal Bose gas
JiÅÃ 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…
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…
Universal quantum dynamics of Bose polarons
JiÅÃ 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…
