Competition between memory-keeping and memory-erasing decoherence channels
Tony J. G. Apollaro, Salvatore Lorenzo, Carlo Di Franco +2
We study the competing effects of simultaneous Markovian and non-Markovian decoherence mechanisms acting on a single spin. We show the existence of a threshold in the relative stre…
Decoherence in a fermion environment: Non-Markovianity and Orthogonality Catastrophe
F. Plastina, A. Sindona, J. Goold +2
We analyze the non-Markovian character of the dynamics of an open two-level atom interacting with a gas of ultra-cold fermions. In particular, we discuss the connection between the…
Effective cutting of a quantum spin chain by bond impurities
T. J. G. Apollaro, F. Plastina, L. Banchi +4
Spin chains are promising media for short-haul quantum communication. Their usefulness is manifested in all those situations where stationary information carriers are involved. In…
Spontaneous synchronization and quantum correlation dynamics of open spin systems
G. L. Giorgi, F. Plastina, G. Francica +1
We discuss the emergence of spontaneous synchronization for an open spin-pair system interacting only via a common environment. Under suitable conditions, and even in the presence…
Geometrical characterization of non-Markovianity
S. Lorenzo, F. Plastina, M. Paternostro
We introduce a new tool for the quantitative characterisation of the departure form Markovianity of a given dynamical process. Our tool can be applied to a generic -level system…
Global quantum correlations in finite-size spin chains
S. Campbell, L. Mazzola, G. De Chiara +4
We perform an extensive study of the properties of global quantum correlations in finite-size one-dimensional quantum spin models at finite temperature. By adopting a recently prop…
