Description:
Author(s): Filippo Giraldi and Francesco Petruccione The decoherence of a qubit is studied for a general class of spectral densities with an arbitrary band gap. The exact dynamics reveals the existence of critical values of the qubit transition frequency, such that relaxations of coherence show discontinuities, jumping from decays with powers arbitrar...
