The problem of time in parametrized theories
Fabian H. Gaioli, Edgardo T. Garcia Alvarez
A common feature of reparametrization invariant theories is the difficulty involved in identifying an appropriate evolution parameter and in constructing a Hilbert space on states.…
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…
On the quantum electrodynamics of moving bodies
Edgardo T. Garcia Alvarez, Fabian H. Gaioli
A new synthesis of the principles of relativity and quantum mechanics is developed by replacing the Poincaré group for the de Sitter one. The new relativistic quantum mechanics is…
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…
