We show that certain quantum systems in non-trivial classical
backgrounds can be mapped into entirely classical systems in
higher dimensions. The evolution of the classical system can
be used to obtain the particle production rate as well as the
quantum backreaction on the classical background. The technique
has many potential applications, including breather/oscillon
dynamics, Hawking radiation and black hole evaporation, and
particle production during inflation.
