Striped twisted state in the orientational epitaxy on quasicrystals
Nicola Manini, Mario Forzanini, Sebastiano Pagano +9
The optimal "twisted" geometry of a crystalline layer on a crystal is long known, but that on a quasicrystal is still unknown and open. We predict analytically that the layer equil…
Phononic frictional losses of a particle crossing a crystal: linear-response theory
Gabriele Riva, Giacomo Piscia, Nicolas Trojani +3
We address weak-coupling frictional sliding with phononic dissipation by means of analytic many-body techniques. Our model consists of a particle (the "slider") moving through a tw…
DC and AC Josephson effects with superfluid Fermi atoms across a Feshbach resonance
L. Salasnich, F. Ancilotto, N. Manini +1
We show that both DC and AC Josephson effects with superfluid Fermi atoms in the BCS-BEC crossover can be described at zero temperature by a nonlinear Schrodinger equation (NLSE).…
Nonlinear hysteretic behavior of a confined sliding layer
N. Manini, G. E. Santoro, E. Tosatti +1
A nonlinear model representing the tribological problem of a thin solid lubricant layer between two sliding periodic surfaces is used to analyze the phenomenon of hysteresis at pin…
Macroscopic Periodic Tunneling of Fermi Atoms in the BCS-BEC Crossover
L. Salasnich, N. Manini, F. Toigo
We study the macroscopic quantum tunneling of two weakly-linked superfluids made of interacting fermionic atoms. We derive atomic Josephson junction equations and find that zero-mo…
Bulk and Collective Properties of a Dilute Fermi Gas in the BCS-BEC Crossover
N. Manini, L. Salasnich
We investigate the zero-temperature properties of a dilute two-component Fermi gas with attractive interspecies interaction in the BCS-BEC crossover. We build an efficient parametr…
