Atomic gases confined in curved geometries are characterized by distinctive features that
are absent in their flat counterparts, such as periodic boundaries, local curvature and …

We review the quantum statistical properties of two-dimensional shell-shaped gases,
produced by cooling and confining atomic ensembles in thin hollow shells. We consider …

Progress in understanding quantum systems has been driven by the exploration of the
geometry, topology, and dimensionality of ultracold atomic systems. The NASA Cold Atom …

Confinement can have a considerable effect on the behavior of particle systems and is
therefore an effective way to discover new phenomena. A notable example is a system of …

We investigate the ground-state properties of N bosons with attractive zero-range
interactions characterized by the scattering length a> 0 and confined to the surface of a …

The control over the geometry and topology of quantum systems is crucial for advancing
novel quantum technologies. This work provides a synthesis of recent insights into the …

Microgravity platforms enable cold atom research beyond experiments in typical laboratories
by removing restrictions due to the gravitational acceleration or compensation techniques …

We show that three-dimensional spherical-shell condensates respond to rotation by forming
two aligned triangular Abrikosov-like vortex lattices on each hemispherical surface. The …

This paper presents a review and perspective on quantum gases in bubble traps. We
emphasize how the idea of realizing shell-shaped condensates emerged and was enabled …

Motivated by the recent experimental realization of ultracold quantum gases in shell
topology, we propose a straightforward implementation of matter-wave lensing techniques …
