Abstract

The Keldysh formalism is used to obtain the form of an even-mode nonequilibrium superconducting system which has an enhanced order parameter. The disequilibrium is created using phonons emitted by a microwave field. We find the entanglement length of the Cooper pairs contained in such a system to be around 1×10⁻²⁴m.
