Lecture

Quantum Langevin Equations

Description

This lecture covers the derivation of the quantum Langevin equation, force correlations, manifestation of the fluctuation-dissipation theorem, input-output formalism, total Hamiltonian of an open quantum system, bath modes, and the forward quantum Langevin equation for a two-level system. It also discusses the motivation for the input-output formalism in LIGO and the quantum regression theorem extended to three operators.
