Controlling decoherence of a two-level-atom in a lossy cavity
M. Thorwart, L. Hartmann, I. Goychuk +1
By use of external periodic driving sources, we demonstrate the possibility of controlling the coherent as well as the decoherent dynamics of a two-level atom placed in a lossy cav…

Driven Tunneling Dynamics: Bloch-Redfield Theory versus Path Integral Approach
Ludwig Hartmann, Igor Goychuk, Milena Grifoni +1
In the regime of weak bath coupling and low temperature we demonstrate numerically for the spin-boson dynamics the equivalence between two widely used but seemingly different roads…
