Quantum Brownian motion
Fabian H. Gaioli, Edgardo T. Garcia Alvarez, Javier Guevara
We study the behavior of a subsystem (harmonic oscillator) in contact with a thermal reservoir (finite set of uncoupled harmonic oscillators). We exactly solve the eigenvalue probl…

Quantum Brownian motion. II
Fabian H. Gaioli, Edgardo T. Garcia Alvarez, Diego G. Arbo
This paper is devoted to generalize some previous results presented in Gaioli et al., Int. J. Theor. Phys. 36, 2167 (1997). We evaluate the autocorrelation function of the stochast…

Covariant Hamiltonian formalisms for particles and antiparticles
Edgardo T. Garcia Alvarez, Fabian H. Gaioli
The hyperplane and proper time formalisms are discussed mainly for the spin-half particles in the quantum case. A connection between these covariant Hamiltonian formalisms is estab…
