Quantum gases in optical boxes

N Navon, RP Smith, Z Hadzibabic - Nature Physics, 2021 - nature.com
Quantum atomic and molecular gases are flexible systems for studies of fundamental many-
body physics. They have traditionally been produced in harmonic electromagnetic traps and …

Superfluid fraction in an interacting spatially modulated Bose-Einstein condensate

G Chauveau, C Maury, F Rabec, C Heintze… - Physical Review Letters, 2023 - APS
At zero temperature, a Galilean-invariant Bose fluid is expected to be fully superfluid. Here
we investigate theoretically and experimentally the quenching of the superfluid density of a …

Impurities and polarons in bosonic quantum gases: a review on recent progress

F Grusdt, N Mostaan, E Demler, LAP Ardila - ar** in a two-dimensional Fermi gas
M Bohlen, L Sobirey, N Luick, H Biss, T Enss… - Physical Review Letters, 2020 - APS
Strongly interacting two-dimensional Fermi systems are one of the great remaining
challenges in many-body physics due to the interplay of strong local correlations and …

Designing arbitrary one-dimensional potentials on an atom chip

M Tajik, B Rauer, T Schweigler, F Cataldini… - Optics express, 2019 - opg.optica.org
We use laser light shaped by a digital micro-mirror device to realize arbitrary optical dipole
potentials for one-dimensional (1D) degenerate Bose gases of^ 87Rb trapped on an atom …

Quantum bubbles in microgravity

A Tononi, F Cinti, L Salasnich - Physical Review Letters, 2020 - APS
The recent developments of microgravity experiments with ultracold atoms have produced a
relevant boost in the study of shell-shaped ellipsoidal Bose-Einstein condensates. For …
