We investigate the Fano-Anderson model coupled to a large ensemble of spins under the influence of an external magnetic field. The interaction between the two spin systems is treated within a meanfield-approach and we assume an anisotropic coupling between these two systems. By using a nonadiabatic approach, we make no further approximations in the theoretical description of our system, apart from the semiclassical treatment. Therewith, we can include the short-time dynamics as well as the… 
Electron transport in nanoscale junctions with local anharmonic modes.
It is shown that the analog of the Franck-Condon blockade physics is missing in the spin-fermion model, and the mean-field analysis of the Anderson-Holstein model suggests that nonlinear functionalities, bistability and hysteresis may develop.
Dynamics of Magnetic Molecules under Electrical Control
This thesis theoretically studies the dynamics of molecular magnets under electrical control. Molecular magnets are nanoscale magnets that can, e.g., consist of single-molecules or single-atoms. In
Dynamical exchange and phase induced switching of a localized molecular spin
We address the dynamics of a localized molecular spin under the influence of external voltage pulses using a generalized spin equation of motion which incorporates anisotropic fields, nonequilibriu


Spin effects in transport through single-molecule magnets in the sequential and cotunneling regimes
We analyze the stationary spin-dependent transport through a single-molecule magnet weakly coupled to external ferromagnetic leads. Using the real-time diagrammatic technique, we calculate the
Transport and semiclassical dynamics of coupled quantum dots interacting with a local magnetic moment
We present a theory of magnetotransport through a system of two coupled electronic orbitals, where the electron spin interacts with a (large) local magnetic moment via an exchange interaction. For
Electron transport through a parallel double-dot system in the presence of Aharonov-Bohm flux and phonon scattering
We examine the transport and microwave properties of the tunnel-coupled double-dot structure with parallel arrangement between leads in the presence of Aharonov-Bohm magnetic flux. The nonequilibrium
Phase transitions in dissipative quantum transport and mesoscopic nuclear spin pumping
Topological phase transitions can occur in the dissipative dynamics of a quantum system when the ratio of matrix elements for competing transport channels is varied. Here we establish a relation
Adiabaticity in semiclassical nanoelectromechanical systems
We compare the semiclassical description of NEMS within and beyond the adiabatic approximation. We consider a NEMS model which contains a single phonon (oscillator) mode linearly coupled to an
Semiclassical dynamics of nanoelectromechanical systems
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 stationary electronic

The purpose of this review is to provide a comprehensive pedagogical introduction into Keldysh technique for interacting out-of-equilibrium fermionic and bosonic systems. The emphasis is placed on a
Limit cycles and chaos in the current through a quantum dot
We investigate nonlinear magnetotransport through a single-level quantum dot coupled to ferromagnetic leads, where the electron spin is coupled to a large, external (pseudo)spin via an anisotropic
