Designing reservoirs for 1/t decoherence of a qubit
Filippo Giraldi, Francesco Petruccione
Anomalous decoherence in the Jaynes-Cummings model emerges for a certain class of bosonic reservoirs, described by spectral densities with a band edge frequency coinciding with the…
Anomalous decay of an atom in structured band gap reservoirs
Filippo Giraldi, Francesco Petruccione
We analyze the spontaneous emission of a two-level atom interacting with a special class of structured reservoirs of field modes with band gap edge coinciding with the atomic trans…
Open system approach to the internal dynamics of a model multilevel molecule
Filippo Giraldi, Francesco Petruccione
A model multilevel molecule described by two sets of rotational internal energy levels of different parity and degenerate ground states, coupled by a constant interaction, is consi…
A reservoir for inverse power law decoherence of a qubit
Filippo Giraldi, Francesco Petruccione
The exact dynamics of a Jaynes-Cummings model for a qubit interacting with a continuous distribution of bosons, characterized by a special form of the spectral density, is evaluate…
