Within Gross-Pitaevskii (GP) theory we derive the interface potential V (l) which describes the interaction between the interface separating two demixed Bose-condensed gases and an optical hard wall at a distance l. Previous work revealed that this interaction gives rise to extraordinary wetting and prewetting phenomena. Calculations that explore non-equilibrium properties by using l as a constraint provide a thorough explanation for this behavior. We find that at bulk two-phase coexistence, V…

Interface tension of Bose-Einstein condensates

Motivated by recent observations of phase-segregated binary Bose-Einstein condensates, we propose a method to calculate the excess energy due to the interface tension of a trapped configuration. By

Line tension near the wetting transition: results from an interface displacement model

Extraordinary wetting phase diagram for mixtures of Bose-Einstein condensates.

The surface of a binary mixture of Bose-Einstein condensates can undergo a first-order wetting phase transition upon varying the interparticle interactions, using, e.g., Feshbach resonances.

LINE TENSION AT WETTING

A review is presented of recent theoretical advances on a fundamental problem in statistical mechanics that concerns the three-phase contact line ℒ and its tension τ near a wetting phase transition.

Quantum gases in optical boxes

Advances in light shaping for optical trapping of neutral particles have led to the development of box traps for ultracold atoms and molecules. These traps have allowed the creation of homogeneous

Capillary Flotation in a System of Two Immiscible Bose–Einstein Condensates

A spatially inhomogeneous, trapped two-component Bose–Einstein condensate of cold atoms in the phase separation mode has been numerically simulated. It has been demonstrated for the first time that

Quantum degenerate mixtures of Cs and Yb

We report the production of quantum degenerate Bose-Bose mixtures of Cs and Yb with both attractive (Cs + $^{174}$Yb) and repulsive (Cs + $^{170}$Yb) interspecies interactions. Dual-species

Breathing Mode of a Bose-Einstein Condensate Immersed in a Fermi Sea.

It is found that the frequency down-shift is caused by the fermion-induced compression and rethermalization of the bosonic species as the system is quenched into the strongly interacting regime.

Parametrically excited star-shaped patterns at the interface of binary Bose-Einstein condensates

A Faraday-wave-like parametric instability is investigated via mean-field and Floquet analysis in immiscible binary Bose-Einstein condensates. The condensates form a so-called \textit{ball-shell}
