Cooperative effects in Josephson junctions in a cavity in the strong coupling regime
Marco Frasca
We analyze the behavior of systems of two and three qubits made by Josephson junctions, treated in the two level approximation, driven by a radiation mode in a cavity. The regime w…
Third order correction to localization in a two-level driven system
Marco Frasca
A general result is presented on the lack of second order corrections and on the form of the leading order Floquet quasi-energies in the high-frequency approximation for a two-leve…
A Quantum Many-Body Instability in the Thermodynamic Limit
Marco Frasca
Intrinsic decoherence in the thermodynamic limit is shown for a large class of many-body quantum systems in the unitary evolution in NMR and cavity QED. The effect largely depends…
Stern-Gerlach Experiment and Bohm Limit
Marco Frasca
Stern-Gerlach experiment is a paradigm of measurement theory in quantum mechanics. Notwithstanding several analysis given in literature, no clear understanding of the apparent coll…
1/N-expansion for the Dicke model and the decoherence program
Marco Frasca
An analysis of the Dicke model, N two-level atoms interacting with a single radiation mode, is done using the Holstein-Primakoff transformation. The main aim of the paper is to sho…
Dynamical decoherence in a cavity with a large number of two-level atoms
Marco Frasca
We consider a large number of two-level atoms interacting with the mode of a cavity in the rotating-wave approximation (Tavis-Cummings model). We apply the Holstein-Primakoff trans…
