One of the important issues in nanomagnetism is to lower the current needed for a technologically useful domain wall (DW) propagation speed. Based on...
Various theoretical methods address transport effects in quantum dots beyond single-electron tunneling while accounting for the strong interactions in...
The model of a two-level system (TLS) coupled to a harmonic oscillator has found a widespread application in physics and chemistry. In this thesis we...
In this thesis we investigate the interplay between dissipation and driving in nonlinear quantum systems for a special setup: a flux qubit read out by...
We study the entanglement spectrum of spin-1/2 XXZ ladders both analytically and numerically. Our analytical approach is based on perturbation theory...
The spin degree of freedom has become subject to one of the broadest and most intensively studied fields of research in physics. The present thesis is...
