Dephasing-rephasing dynamics of one-dimensional tunneling quasicondensates
Andrea Tononi, Flavio Toigo, Sandro Wimberger +2
We study the quantum tunneling of two one-dimensional quasi-condensates made of alkali-metal atoms, considering two different tunneling configurations: side-by-side and head-to-tai…
Collisionless Dynamics in Two-Dimensional Bosonic Gases
A. Cappellaro, F Toigo, L. Salasnich
We study the dynamics of dilute and ultracold bosonic gases in a quasi two-dimensional (2D) configuration and in the collisionless regime. We adopt the 2D Landau-Vlasov equation to…

We analyze the divergent zero-point energy of a dilute and ultracold gas of atoms in D spatial dimensions. For bosonic atoms we explicitly show how to regularize this divergent con…

We study the real-time motion of a microscopic object in a cold Fermi gas at unitary conditions by using an extended Thomas-Fermi density functional approach. We find that spontane…
