Spin-boson dynamics beyond conventional perturbation theories
Francesco Nesi, Elisabetta Paladino, Michael Thorwart +1
A novel approximation scheme is proposed to describe the dynamics of the spin-boson problem. Being nonperturbative in the coupling strength nor in the tunneling frequency, it gives…

Dynamics of a qubit coupled to a broadened harmonic mode at finite detuning
F. Nesi, M. Grifoni, E. Paladino
We study the dynamics of a symmetric two-level system strongly coupled to a broadened harmonic mode. Upon mapping the problem onto a spin-boson model with peaked spectral density,…
