Smirnov, Sergey and Grifoni, Milena (2012) Spin-channel Keldysh field theory for weakly interacting quantum dots. Phys. Rev. B 85, p. 195310.
We develop a low-energy nonequilibrium field theory for weakly interacting quantum dots. The theory is based on the Keldysh field integral in the spin channel of the quantum dot described by the single-impurity Anderson Hamiltonian. The effective Keldysh action is a functional of the Hubbard-Stratonovich magnetization field decoupling the quantum dot spin channel. We expand this action up to the ...
