โœฆ Synopsis

We derive the exact action for a damped mechanical system (and the special case of the linear oscillator) from the path integral formulation of the quantum Brownian motion problem developed by Schwinger and by Feynman and Vernon. The doubling of the phasespace degrees of freedom for dissipative systems and thermal field theories is discussed and the initial values of the doubled variables are related to quantum noise effects. 1.1995 Academic Press.

A key simulation issue is the development of a dissipation formalism for the time dependent density operator equation, that is amenable to numerical methods and incorporates the role of the environment on state renormalization and dissipation. Using standard super-operator calculus, projection opera
