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…
Beyond-mean-field analysis of the Townes soliton and its breathing mode
D. S. Petrov
By using the Bogoliubov perturbation theory we describe the self-bound ground state and excited breathing states of two-dimensional bosons with zero-range attractive interactio…
Absence of binding of heavy fermions by two light atoms in two dimensions
J. Givois, D. S. Petrov
By developing the mean-field theory valid for large , we investigate the problem of two light fermions interacting via a zero-range potential with heavy fermions in two dime…
Gas-to-soliton transition of attractive bosons on a spherical surface
A. Tononi, G. E. Astrakharchik, D. S. Petrov
We investigate the ground state properties of bosons with attractive zero-range interactions characterized by the scattering length and confined to the surface of a spher…
Heavy-light clusters of two-dimensional fermions
J. Givois, A. Tononi, D. S. Petrov
We study binding of identical heavy fermions by a light atom in two dimensions assuming zero-range attractive heavy-light interactions. By using the mean-field theory valid for…
