Density profile of a BoseEinstein condensate inside a pancakeshaped trap: Observational consequences of the dimensional crossover in the scattering properties
Tanatar, Bilal; Minguzzi, A.; Vignolo, P.; Tosi, M. P. (Elsevier Science B.V., 2002)It is theoretically well known that twodimensionality of the scattering events in a BoseEinstein condensate introduces a logarithmic dependence on density in the coupling constant entering a meanfield theory of the ... 
Dimensional crossover in twodimensional BoseFermi mixtures
Subaşi, A. L.; Sevinçli, S.; Vignolo, P.; Tanatar, Bilal (Institute of Physics Publishing, 2010)We investigate the equilibrium properties of bosonfermion mixtures consisting of a Bose condensate and spinpolarized Fermi gas confined in a harmonic twodimensional (2D) trap using meanfield theory. Bosonboson and ... 
Free expansion of twodimensional condensates with a vortex
Hoşten, O.; Vignolo, P.; Minguzzi, A.; Tanatar, Bilal; Tosi, M. P. (Institute of Physics Publishing, 2003)We study the free expansion of a pancakeshaped Bosecondensed gas, which is initially trapped under harmonic confinement and containing a vortex at its centre. In the case of a radial expansion holding the axial confinement ... 
Metalinsulator transition induced by random dipoles
Larcher, M.; Menotti, C.; Tanatar, Bilal; Vignolo, P. (American Physical Society, 2013)We study the localization properties of a test dipole feeling the disordered potential induced by dipolar impurities trapped at random positions in an optical lattice. This random potential is marked by correlations which ... 
Temperature dependence of the energy of a vortex in a twodimensional Bose gas
Rajagopal, K. K.; Tanatar, Bilal; Vignolo, P.; Tosi, M. P. (Elsevier, 2004)We evaluate the thermodynamic critical angular velocity Ωc(T) for creation of a vortex of lowest quantized angular momentum in a strictly twodimensional Bose gas at temperature T, using a meanfield twofluid model for ...
