  • Title: Quantum Brownian motion with large friction.
    Author: Ankerhold J, Grabert H, Pechukas P.
    Journal: Chaos; 2005 Jun; 15(2):26106. PubMed ID: 16035908.
    Abstract:
    Quantum Brownian motion in the strong friction limit is studied based on the exact path integral formulation of dissipative systems. In this limit the time-nonlocal reduced dynamics can be cast into an effective equation of motion, the quantum Smoluchowski equation. For strongly condensed phase environments it plays a similar role as master equations in the weak coupling range. Applications for chemical, mesoscopic, and soft matter systems are discussed and reveal the substantial role of quantum fluctuations.
