Geometric filtering effect in expanding Bose-Einstein condensate shells
Andrea Tononi, Maciej Lewenstein, Luis Santos
A shell-shaped Bose-Einstein condensate released from its confinement expands radially both outwards and inwards, displaying a self-interference pattern characterized by a density…
Spatial Leggett-Garg inequalities
Guillem Müller-Rigat, Donato Farina, Maciej Lewenstein +1
We formulate a spatial extension of the Leggett-Garg inequality by considering three distant observers locally measuring a many-body system at three subsequent times. The spatial f…
Bose-Einstein condensation on axially-symmetric surfaces
A. Tononi, G. E. Astrakharchik
We investigate the phenomenon of Bose-Einstein condensation in ideal bosonic gases confined to axially-symmetric surfaces of revolution. The single-particle Schrödinger equation is…
Dimer problem on a spherical surface
A. Tononi, D. S. Petrov, M. Lewenstein
We solve the problem of a dimer moving on a spherical surface and find that its binding energy and wave function are sensitive to the total angular momentum. The dimer gets squeeze…
