Description

The Feynman-Vernon path integral formalism is a powerful tool for studying open quantum systems. As a concrete example, quantum Brownian motion may be studied using the theory of open quantum systems. The goal of the first lecture will be to outline the Caldeira-Leggett model for quantum Brownian motion. The goal of the second lecture will be to introduce the Feynman-Vernon path integral formalism for open quantum systems and then to apply it to the Caldeira-Leggett model for quantum Brownian motion.

  • Basic formalism of the Feynman-Vernon path integral.
  • Apply this formalism to the above model.
  • Use this formalism to re-derive the exact equations of motions.
