Description

Input–output theory is a well–known tool in cavity elec-
trodynamics and ubiquitous in the description of quantum
systems interacting with the environment. We present a
new approach to input–output theory using the Keldysh path
integral formalism. This approach allows us to get perturbative results for non–linear systems.
We apply this novel approach to a single mode in a cavity
solvable through standard input–output theory
and then treat a Kerr oscillator to showcase the spe-
cific strength of our approach to yield perturbative results.
