A ug 2 00 7 Fredholm determinants and the statistics of charge transport
Using operator algebraic methods we show that the moment generating function of charge transport in a system with infinitely many non-interacting Fermions is given by a determinant of a certain operator in the one-particle Hilbert space. The formula is equivalent to a formula of Levitov and Lesovik in the finite dimensional case and may be viewed as its regularized form in general. Our result e...

The Anderson model of local-state conduction electron mixing is applied to the problem of interlayer magnetic coupling in metallic multilayered structures with palladium (Pd) spacer layers. An oscillation period of 5 spacer monolayers and the tendency towards ferromagnetic bias of the interlayer magnetic coupling that we obtain are consistent with the experimental data. The discovery of oscilla...

We develop a non–equilibrium many–body theory of the coherent femtosec-ond nonlinear optical response of the Fermi edge singularity. We study the role of the dynamical Fermi sea response in the time–evolution of the pump–probe spectra. The electron–hole correlations are treated nonperturbatively with the time–dependent coupled cluster cxpansion combined with the effective Hamil-tonian approach....
