Expansion of a quantum gas in a shell trap
New Journal of Physics, 2022 We report the observation of the controlled expansion of a two-dimensional (2D) quantum gas confined onto a curved shell-shaped surface. We start from the ellipsoidal geometry of a dressed quadrupole trap and introduce a novel gravity compensation ...

Mixtures of Dipolar Gases in Two Dimensions: A Quantum Monte Carlo Study
Condensed Matter, 2022 We studied the miscibility of two dipolar quantum gases in the limit of zero temperature. The system under study is composed of a mixture of two Bose gases with dominant dipolar interaction in a two-dimensional harmonic confinement.

Quantum gases in trimerized kagom\'e lattices [PDF]
, 2005 We study low temperature properties of atomic gases in trimerized optical kagom\'{e} lattices. The laser arrangements that can be used to create these lattices are briefly described.

Quantum criticality and the Tomonaga-Luttinger liquid in one-dimensional Bose gases. [PDF]
Physical Review Letters, 2016 We experimentally investigate the quantum criticality and Tomonaga-Luttinger liquid (TLL) behavior within one-dimensional (1D) ultracold atomic gases.

Optimal strategies for optical quantum memories using long-lived noble-gas spins
Physical Review ResearchNuclear spins of noble gases exhibit exceptionally long coherence times and can potentially serve as a long-lived storage medium for quantum information. We analyze and compare the performance of two mechanisms for mapping the quantum state of light onto

Glimmers of a Quantum KAM Theorem: Insights from Quantum Quenches in One-Dimensional Bose Gases
Physical Review X, 2015 Real-time dynamics in a quantum many-body system are inherently complicated and hence difficult to predict. There are, however, a special set of systems where these dynamics are theoretically tractable: integrable models.

Coherent splitting of two-dimensional Bose gases in magnetic potentials
New Journal of Physics, 2020 Investigating out-of-equilibrium dynamics with two-dimensional (2D) systems is of widespread theoretical interest, as these systems are strongly influenced by fluctuations and there exists a superfluid phase transition at a finite temperature.

Magnetic lattices for ultracold atoms and degenerate quantum gases [PDF]
, 2016 We review recent developments in the use of magnetic lattices as a complementary tool to optical lattices for trapping periodic arrays of ultracold atoms and degenerate quantum gases.
