Effects of higher-order Casimir-Polder interactions on Rydberg atom spectroscopy
Biplab Dutta, Joao Carlos de Aquino Carvalho, Guadalupe Garcia-Arellano +5
In the extreme near-field, when the spatial extension of the atomic wavefunction is no longer negligible compared to the atom-surface distance, the dipole approximation is no longe…
Measuring densities of cold atomic clouds smaller than the resolution limit
Andrea Litvinov, Pierre Bataille, Etienne Maréchal +4
We propose and demonstrate an experimental method to measure by absorption imaging the size and local column density of a cloud of atoms, even when its smallest dimension is smalle…
Excitation spectrum and supersolidity of a two-leg bosonic ring ladder
Nicolas Victorin, Paolo Pedri, Anna Minguzzi
We consider a system of weakly interacting bosons confined on a planar double lattice ring subjected to two artificial gauge fields. This system is known to display three phases, t…
Oscillations and decay of superfluid currents in a one-dimensional Bose gas on a ring
Juan Polo, Romain Dubessy, Paolo Pedri +2
We study the time evolution of a supercurrent imprinted on a one-dimensional ring of interacting bosons in the presence of a defect created by a localized barrier. Depending on int…
Collective spin modes of a trapped quantum ferrofluid
S. Lepoutre, L. Gabardos, K. Kechadi +5
We report on the observation of a collective spin mode in a spinor Bose-Einstein condensate. Initially, all spins point perpendicular to the external magnetic field. The lowest ene…
Dissipative cooling of spin chains by a bath of dipolar particles
M. Robert-de-Saint-Vincent, P. Pedri, B. Laburthe-Tolra
We consider a spin chain of fermionic atoms in an optical lattice, interacting with each other by super-exchange interactions. We theoretically investigate the dissipative evolutio…
