Partial self-consistency and analyticity in many-body perturbation theory: particle number conservation and a generalized sum rule
Daniel Karlsson, Robert van Leeuwen
We consider a general class of approximations which guarantees the conservation of particle number in many-body perturbation theory. To do this we extend the concept of -derivab…

Phononic heat transport in the transient regime: An analytic solution
Riku Tuovinen, Niko Säkkinen, Daniel Karlsson +2
We investigate the time-resolved quantum transport properties of phonons in arbitrary harmonic systems connected to phonon baths at different temperatures. We obtain a closed analy…

Effective bias and potentials in steady-state quantum transport: A NEGF reverse-engineering study
Daniel Karlsson, Claudio Verdozzi
Using non-equilibrium Green's functions combined with many-body perturbation theory, we have calculated steady-state densities and currents through short interacting chains subject…
