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…
Observation of an Inverse Turbulent-Wave Cascade in a Driven Quantum Gas
Andrey Karailiev, Martin Gazo, Maciej Gałka +3
We observe an inverse turbulent-wave cascade, from small to large lengthscales, in a driven homogeneous 2D Bose gas. Starting with an equilibrium condensate, we drive the gas isotr…
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…
Universal Coarsening in a Homogeneous Two-Dimensional Bose Gas
Martin Gazo, Andrey Karailiev, Tanish Satoor +3
Coarsening of an isolated far-from-equilibrium quantum system is a paradigmatic many-body phenomenon, relevant from subnuclear to cosmological lengthscales, and predicted to featur…
