Quantum fluctuations in superconducting dots at finite temperature
G. Falci, A. Fubini
We study the thermodynamics of ultrasmall metallic grains with level spacing comparable or smaller than the pairing correlation energy, at finite temperatures, $T \gsim δ$. We…

Detection of Geometric Phases in Superconducting Nanocircuits
Giuseppe Falci, Rosario Fazio, G. Massimo Palma +2
When a quantum mechanical system undergoes an adiabatic cyclic evolution it acquires a geometrical phase factor in addition to the dynamical one. This effect has been demonstrated…

The BCS model and the off shell Bethe ansatz for vertex models
Luigi Amico, G. Falci, Rosario Fazio
We study the connection between the BCS pairing model and the inhomogeneous vertex model. The two spectral problems coincide in the quasi-classical limit of the off-shell Bethe Ans…
