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…
Composite bosons in the 2D BCS-BEC crossover from Gaussian fluctuations
L. Salasnich, F. Toigo
We study Gaussian fluctuations of the zero-temperature attractive Fermi gas in the 2D BCS-BEC crossover showing that they are crucial to get a reliable equation of state in the BEC…
Superfluidity, Sound Velocity and Quasi Condensation in the 2D BCS-BEC Crossover
L. Salasnich, P. A. Marchetti, F. Toigo
We study finite-temperature properties of a two-dimensional superfluid made of ultracold alkali-metal atoms in the BCS-BEC crossover. We investigate the region below the critical t…
Collective modes in the anisotropic unitary Fermi gas and the inclusion of a backflow term
L. Salasnich, P. Comaron, M. Zambon +1
We study the collective modes of the confined unitary Fermi gas under anisotropic harmonic confinement as a function of the number of atoms. We use the equations of extended superf…
Shock waves in strongly interacting Fermi gas from time-dependent density functional calculations
F. Ancilotto, L. Salasnich, F. Toigo
Motivated by a recent experiment [Phys. Rev. Lett. 106, 150401 (2011)] we simulate the collision between two clouds of cold Fermi gas at unitarity conditions by using an extended T…
Rabi-Josephson oscillations and self-trapped dynamics in atomic junctions with two bosonic species
G. Mazzarella, B. Malomed, L. Salasnich +2
We investigate the dynamics of two-component Bose-Einstein condensates (BECs), composed of atoms in two distinct hyperfine states, which are linearly coupled by two-photon Raman tr…
