Slave-boson Keldysh field theory for the Kondo effect in quantum dots

Smirnov, Sergey ; Grifoni, Milena



Abstract

We present a nonequilibrium nonperturbative field theory for the Kondo effect in strongly interacting quantum dots at finite temperatures. Unifying the slave-boson representation with the Keldysh field integral, an effective Keldysh action is derived and explored in the vicinity of the zero slave-bosonic field configuration. The theory properly reflects the essential features of the Kondo physics ...
