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…
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(…
Observation of subdiffusive dynamic scaling in a driven and disordered Bose gas
Gevorg Martirosyan, Christopher J. Ho, Jiří Etrych +4
We explore the dynamics of a tuneable box-trapped Bose gas under strong periodic forcing in the presence of weak disorder. In absence of interparticle interactions, the interplay o…
Universal equation of state for wave turbulence in a quantum gas
Lena H. Dogra, Gevorg Martirosyan, Timon A. Hilker +6
Boyle's 1662 observation that the volume of a gas is, at constant temperature, inversely proportional to pressure, offered a prototypical example of how an equation of state (EoS)…
Pinpointing Feshbach Resonances and Testing Efimov Universalities in K
Jiří Etrych, Gevorg Martirosyan, Alec Cao +5
Using a combination of bound-state spectroscopy and loss spectroscopy, we pinpoint eight intrastate Feshbach resonances in K, as well as six previously unexplored interstate…
