Multidimensional solitons in a low-dimensional periodic potential
B. B. Baizakov, B. A. Malomed, M. Salerno
Using the variational approximation(VA) and direct simulations, we find stable 2D and 3D solitons in the self-attractive Gross-Pitaevskii equation (GPE) with a potential which is u…
Superfluid Dynamics of a Bose-Einstein Condensate in a Periodic Potential
C. Menotti, A. Smerzi, A. Trombettoni
We investigate the superfluid properties of a Bose-Einstein condensate (BEC) trapped in a one dimensional periodic potential. We study, both analytically (in the tight binding limi…
Phase separation of incompressible binary fluids with Lattice Boltzmann Methods
Aiguo Xu, G. Gonnella, A. Lamura
We introduce new versions of lattice Boltzmann methods (LBM) for incompressible binary mixtures where fluctuations of total density are inhibited. As a test for the improved algori…
Liquid-Liquid Phase Transitions for Soft-Core Attractive Potentials
A. Skibinsky, S. V. Buldyrev, G. Franzese +2
Using event driven molecular dynamics simulations, we study a three dimensional one-component system of spherical particles interacting via a discontinuous potential combining a re…
Intermittency of glassy relaxation and the emergence of a non-equilibrium spontaneous measure in the aging regime
A. Crisanti, F Ritort
We consider heat exchange processes between non-equilibrium aging systems (in their activated regime) and the thermal bath in contact. We discuss a scenario where two different hea…
Delocalizing transition of multidimensional solitons in Bose-Einstein condensates
B. B. Baizakov, M. Salerno
Critical behavior of solitonic waveforms of Bose-Einstein condensates in optical lattices (OL) has been studied in the framework of continuous mean-field equation. In 2D and 3D OLs…
Motion of a heavy impurity through a Bose-Einstein condensate
G. E. Astrakharchik, L. P. Pitaevskii
We study motion of a point-like impurity in a Bose-Einstein condensate at T=0. By solving the Gross-Pitaevskii equation in a perturbative manner we calculate the induced mass of th…
Regular spatial structures in arrays of Bose-Einstein condensates induced by modulational instability
B. B. Baizakov, V. V. Konotop, M. Salerno
We show that the phenomenon of modulational instability in arrays of Bose-Einstein condensates confined to optical lattices gives rise to coherent spatial structures of localized e…
Stable two-dimensional dispersion-managed soliton
F. Kh. Abdullaev, B. B. Baizakov, M. Salerno
The existence of a dispersion-managed soliton in two-dimensional nonlinear Schrödinger equation with periodically varying dispersion has been explored. The averaged equations for t…
Bogoliubov spectrum and Bragg spectroscopy of elongated Bose-Einstein condensates
Cesare Tozzo, Franco Dalfovo
The behavior of the momentum transferred to a trapped Bose-Einstein condensate by a two-photon Bragg pulse reflects the structure of the underlying Bogoliubov spectrum. In elongate…
Theoretical description of phase coexistence in model C60
D. Costa, G. Pellicane, C. Caccamo +2
We have investigated the phase diagram of the Girifalco model of C60 fullerene in the framework provided by the MHNC and the SCOZA liquid state theories, and by a Perturbation Theo…
Smectic ordering of parallel hard spherocylinders: An entropy-based Monte Carlo study
D. Costa, F. Saija, P. V. Giaquinta
We investigated the nematic to smectic transition undergone by parallel hard spherocylinders in the framework provided by the residual multi-particle entropy (RMPE) formalism. The…
Slow dynamics of a confined supercooled binary mixture: direct space analysis
P. Gallo, R. Pellarin, M. Rovere
Dynamical properties of a Lennard-Jones binary mixture embedded in an off lattice matrix of soft spheres are studied in the direct space upon supercooling by molecular dynamics sim…
