Existence of a Semiclassical Approximation in Loop Quantum Gravity
Marco Frasca
We consider a spherical symmetric black hole in the Schwarzschild metric and apply Bohr-Sommerfeld quantization to determine the energy levels. The canonical partition function is…
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…
Fully polarized states and decoherence
Marco Frasca
The aim of this review is to show how ``ferromagnetic'' states, that is, states having a fully polarization, can produce intrinsic decoherence by unitary evolution. This effect can…
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…
