Josephson nanocircuit in the presence of linear quantum noise
E. Paladino, F. Taddei, G. Giaquinta +1
We derive the effective hamiltonian for a charge-Josephson qubit in a circuit with no use of phenomenological arguments, showing how energy renormalizations induced by the environm…
Quasi-classical descendants of disordered vertex models with boundaries
Antonio Di Lorenzo, Luigi Amico, Kazuhiro Hikami +2
We study descendants of inhomogeneous vertex models with boundary reflections when the spin-spin scattering is assumed to be quasi--classical. This corresponds to consider certain…
The Quantum Dissipative Villain Model
G. Falci, G. Giaquinta, U. Weiss
We introduce the Quantum Dissipative Villain (QDV) model as a prototype model to study tunneling in dissipative quantum mechanics. Dissipation is provided by a coupled linear envir…
Supersolid phase in fully frustrated Josephson junction arrays
Luigi Amico, Giuseppe Falci, Rosario Fazio +1
We study the phase diagram and the excitation spectra of an array of small Josephson junctions at and arbitrary charge frustration. We find that the supersolid region in th…
