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 qubit transition fr...
Entanglement dynamics of bipartite system in squeezed vacuum reservoirs
squeezed vacuum reservoirs bipartite system Quantum Physics
