Fermi Liquid Theory for the Nonequilibrium Kondo Effect at Low Bias Voltages
Fermi Liquid Theory for the Nonequilibrium Kondo Effect at Low Bias Voltages
In this report, we describe a recent development in a Fermi liquid theory for the Kondo effect in quantum dots under a finite bias voltage $V$. Applying the microscopic theory of Yamada and Yosida to a nonequilibrium steady state, we derive the Ward identities for the Keldysh Green's function, and …
