Parametric down conversion of a bosonic thermofield vacuum [PDF]
Thiago PrudencioWe consider a process of parametric down conversion where the input state is a bosonic thermofield vacuum. This state leads to a parametric down conversion, generating an output of two excited photons. Following a thermofield dynamics scheme, the input state, initially in a bosonic thermofield vacuum, and the output states, initially in vacuum states, evolve under a Liouville-von Neumann equation.View original: http://arxiv.org/abs/1209.0509
