A Dyson equation for non-equilibrium Green's functions in the partition-free setting
H. D. Cornean, V. Moldoveanu, C. -A. Pillet
We consider a small interacting sample coupled to several non-interacting leads. Initially, the system is at thermal equilibrium. At some instant the system is set into the s…
A mathematical account of the NEGF formalism
H. D. Cornean, V. Moldoveanu, C. -A. Pillet
The main goal of this paper is to put on solid mathematical grounds the so-called Non-Equilibrium Green's Function (NEGF) transport formalism for open systems. In particular, we de…
On the steady state correlation functions of open interacting systems
Horia D. Cornean, Claude-Alain Pillet, Valeriu Moldoveanu
We address the existence of steady state Green-Keldysh correlation functions of interacting fermions in mesoscopic systems for both the partitioning and partition-free scenarios. U…
The dynamics of 1D Bloch electrons in constant electric fields
F. Bentosela, P. Duclos, G. Nenciu +1
We study the dynamics of a 1D Bloch electron subjected to a constant electric field. The periodic potential is supposed to be less singular than the -like potential (Dirac comb)…
