Thermodynamic Limit and Decoherence: Rigorous Results
Marco Frasca
Time evolution operator in quantum mechanics can be changed into a statistical operator by a Wick rotation. This strict relation between statistical mechanics and quantum evolution…
Proof of triviality of theory
Marco Frasca
We show that a recent analysis in the strong coupling limit of the theory proves that this theory is indeed trivial giving in this limit the expansion of a free quantum fiel…
Infrared analysis of quantum field theories
Marco Frasca
We show that for a theory having many components, the solution with all equal components in the infrared regime is stable with respect to our expansion given by a recently d…
Localization in a strongly disordered system: A perturbation approach
Marco Frasca
We prove that a strongly disordered two-dimensional system localizes with a localization length given analytically. We get a scaling law with a critical exponent is in agreem…
A strongly perturbed quantum system is a semiclassical system
Marco Frasca
We show that a strongly perturbed quantum system, being a semiclassical system characterized by the Wigner-Kirkwood expansion for the propagator, has the same expansion for the eig…
