Mesoscopic BCS pairing in the repulsive 1d-Hubbard model
Luigi Amico, Andrea Mastellone, Andreas Osterloh
We study mesoscopic pairing in the one dimensional repulsive Hubbard model and its interplay with the BCS model in the canonical ensemble. The key tool is comparing the Bethe ansat…
Dynamical suppression of telegraph and 1/f noise due to quantum bistable fluctuator
G. Falci, A. D'Arrigo, A. Mastellone +1
We study dynamical decoupling of a qubit from non gaussian quantum noise due to discrete sources, as bistable fluctuators and 1/f noise. We obtain analytic and numerical results fo…
Interplay between pairing and exchange in small metallic dots
G. Falci, Rosario Fazio, A. Mastellone
We study the effects of the mesoscopic fluctuations on the competition between exchange and pairing interactions in ultrasmall metallic dots when the mean level spacing is comparab…
Mesoscopic fluctuations in superconducting dots at finite temperatures
G. Falci, A. Fubini, A. Mastellone
We study the thermodynamics of ultrasmall metallic grains with the mean level spacing comparable or larger than the pairing correlation energy in the whole range of temperatures. A…
