Keldysh formalism

In condensed matter physics, the Keldysh formalism describes the evolution of quantum mechanical states in the presence of a time varying magnetic field. It is related to the non-equilibrium Green's function.

References [1] to [4] give the usage of Keldysh formalism in the Rashba model and related models.
