Exact time evolution in harmonic quantum Brownian motion
Fabian H. Gaioli, Edgardo T. Garcia Alvarez
We consider a particular (exactly soluble) model of the one discussed in a previous work. We show numerical results for the time evolution of the main dynamical quantities and comp…
The Gamow vectors and the Schwinger effect
Fabian H. Gaioli, Edgardo T. Garcia Alvarez, Mario A. Castagnino
We introduce a `proper time' formalism to study the instability of the vacuum in a uniform external electric field due to particle production. This formalism allows us to reduce a…
Exact derivation of the Langevin and master equations for harmonic quantum Brownian motion
Edgardo T. Garcia Alvarez, Fabian H. Gaioli
A many particle Hamiltonian, where the interaction term conserves the number of particles, is considered. A master equation for the populations of the different levels is derived i…
