Reliable equation of state for composite bosons in the 2D BCS-BEC crossover
L. Salasnich
We briefly discuss recent experiments on the BCS-BEC crossover with ultracold alkali-metal atoms both in three-dimensional configurations and two-dimensional ones. Then we analyze…
Diffusive Limits of the Master Equation in Inhomogeneous Media
F. Sattin, A. Bonato, L. Salasnich
Diffusion is the macroscopic manifestation of disordered molecular motion. Mathematically, diffusion equations are partial differential equations describing the fluid-like large-sc…
Localized-Interaction-Induced Quantum Reflection and Filtering of Bosonic Matter in a One-Dimensional Lattice Guide
L. Barbiero, B. A. Malomed, L. Salasnich
We study the dynamics of quantum bosonic waves confined in a one-dimensional tilted optical lattice. The bosons are under the action of an effective spatially localized nonlinear t…
Photon-induced Self Trapping and Entanglement of a Bosonic Josephson Junction Inside an Optical Resonator
P. Rosson, G. Mazzarella, G. Szirmai +1
We study the influence of photons on the dynamics and the ground state of the atoms in a Bosonic Josephson junction inside an optical resonator. The system is engineered in such a…
Dimensional reduction and localization of a Bose-Einstein condensate in a quasi-1D bichromatic optical lattice
L. Salasnich, S. K. Adhikari
We analyze the localization of a Bose-Einstein condensate (BEC) in a one-dimensional bichromatic quasi-periodic optical-lattice potential by numerically solving the 1D Gross-Pitaev…
Beliaev damping of the Goldstone mode in atomic Fermi superfluids
G. Bighin, L. Salasnich, P. A. Marchetti +1
Beliaev damping in a superfluid is the decay of a collective excitation into two lower frequency collective excitations; it represents the only decay mode for a bosonic collective…
