Ultracold dipolar gases - a challenge for experiments and theory
, 2002 We present a review of recent results concerning the physics of ultracold trapped dipolar gases. In particular, we discuss the Bose-Einstein condensation for dipolar Bose gases and the BCS transition for dipolar Fermi gases.

EPJ Web of Conferences, 2017 Recently, we have reported a novel role of pairing in low-energy heavy ion reactions at energies above the Coulomb barrier, which may have a detectable impact on reaction outcomes, such as the kinetic energy of fragments and the fusion cross section ...

A dark state of Chern bands: Designing flat bands with higher Chern number
SciPost Physics, 2021 We introduce a scheme by which flat bands with higher Chern number $\vert C\vert>1$ can be designed in ultracold gases through a coherent manipulation of Bloch bands.

High phase-space density gas of NaCs Feshbach molecules
Physical Review Research, 2022 We report on the creation of ultracold gases of bosonic Feshbach molecules of NaCs. The molecules are associated from overlapping gases of Na and Cs using a Feshbach resonance at 864.12(5)G.

Few-body physics in resonantly interacting ultracold quantum gases
, 2017 We provide a general discussion on the importance of three-body Efimov physics for strongly interacting ultracold quantum gases. Using the adiabatic hyperspherical representation, we discuss a universal classification of three-body systems in terms of ...

Vortex dynamics in the two-dimensional BCS-BEC crossover
Nature Communications, 2022 The crossover between the limiting ground states of fermionic systems, the so called BCS-BEC crossover, is of interest to superconductor and ultracold atomic gases communities.

Disorder and interference: localization phenomena [PDF]
, 2016 The specific problem we address in these lectures is the problem of transport and localization in disordered systems, when interference is present, as characteristic for waves, with a focus on realizations with ultracold atoms.Comment: Notes of a lecture

Thermodynamics of Ultracold Fermi Gases [PDF]
Latin America Optics and Photonics Conference, 2010 Les gaz ultrafroids permettent d'étudier sous un angle nouveau des hamiltoniens complexes issus de la matière condensée, tels le modèle de Fermi-Hubbard. Cette thèse présente une nouvelle méthode de mesure de l'équation d'état d'un gaz ultrafroid, autorisant une comparaison directe avec la théorie.

Optimal control of Bose–Einstein condensates in three dimensions
New Journal of Physics, 2015 Ultracold gases promise many applications in quantum metrology, simulation and computation. In this context, optimal control theory (OCT) provides a versatile framework for the efficient preparation of complex quantum states.
