Noise calculations within the second-order von Neumann approach
Philipp Zedler, Clive Emary, Tobias Brandes +1
We extend the second-order von Neumann approach within the generalized master equation formalism for quantum electronic transport to include the counting field. The resulting non-M…
Semi-classical dynamics of nano-electromechanical systems
R. Hussein, A. Metelmann, P. Zedler +1
We investigate the dynamics of a single phonon (oscillator) mode linearly coupled to an electronic few-level system in contact with external particle reservoirs (leads). A stationa…
Weak coupling approximations in non-Markovian Transport
Philipp Zedler, Gernot Schaller, Gerold Kießlich +2
We study the transport properties of the Fano-Anderson model with a Lorentzian-shaped density of states in one of the electronic reservoirs. We explicitly show that the energy depe…
Systematic Perturbation Theory for Dynamical Coarse-Graining
Gernot Schaller, Philipp Zedler, Tobias Brandes
We demonstrate how the dynamical coarse-graining approach can be systematically extended to higher orders in the coupling between system and reservoir. Up to second order in the co…
Ferromagnetism in one-dimensional metals: breakdown of the Hartree-Fock approximation and possible first order phase transition
Philipp Zedler, Peter Kopietz
We calculate the Gibbs potential Gamma (M) of a one-dimensional metal at constant magnetization M to second order in the screened electron-electron interaction U. At zero temperatu…
