Shift of the critical temperature in superconductors: a self-consistent approach
Alberto Cappellaro, Luca Salasnich
Within the Ginzburg-Landau functional framework for the superconducting transition, we analyze the fluctuation-driven shift of the critical temperature. In addition to the order pa…
Effective field theory of bosons with finite-range interaction in a disordered environment
Alberto Cappellaro, Luca Salasnich
We investigate the low-temperature properties of a ultracold gas made of bosonic alkali-metal atoms with finite-range interaction under the effect of a disordered environment. The…
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…
Action Functional for a Particle with Damping
Federico de Bettin, Alberto Cappellaro, Luca Salasnich
In this brief report we discuss the action functional of a particle with damping, showing that it can be obtained from the dissipative equation of motion through a modification whi…
Superfluids, Fluctuations and Disorder
Alberto Cappellaro, Luca Salasnich
We present a field-theory description of ultracold bosonic atoms in presence of a disordered external potential. By means of functional integration techniques, we aim to investigat…
Condensation and superfluidity of dilute Bose gases with finite-range interaction
A. Tononi, A. Cappellaro, L. Salasnich
We investigate an ultracold and dilute Bose gas by taking into account a finite-range two-body interaction. The coupling constants of the resulting Lagrangian density are related t…
