Abordagem via integrais de trajetória do processo de troca e dissipação de energia num sistema composto por dois osciladores harmônicos dissipativos acoplados - o modelo duplicado de Caldeira & Leggett.
Abstract
In this work, we analyse the dissipation and interchange of energy in a
system composed by two harmonic oscillators, each one associated with a thermal
reservoir.
To this end, we employ the Caldeira & Leggett approach, based on path
integral formulation, to obtain the time evolution of the reduced density operator
of the system composed by both oscillators.
