Orthogonality catastrophe and decoherence in a trapped-Fermion environment
A. Sindona, J. Goold, N. Lo Gullo +2
The Fermi edge singularity and the Anderson orthogonality catastrophe describe the universal physics which occurs when a Fermi sea is locally quenched by the sudden switching of a…
Discording power of quantum evolutions
F. Galve, F. Plastina, M. G. A. Paris +1
We introduce the discording power of a unitary transformation, which assesses its capability to produce quantum discord, and analyze in detail the generation of discord by relevant…
Transport of Quantum Correlations across a spin chain
Tony J. G. Apollaro, Salvatore Lorenzo, Francesco Plastina
Some of the recent developments concerning the propagation of quantum correlations across spin channels are reviewed. In particular, we focus on the improvement of the transport ef…
Dynamics of Atom-Atom Correlations in the Fermi problem
Massimo Borrelli, Carlos Sabín, Gerardo Adesso +2
We present a detailed perturbative study of the dynamics of several types of atom-atom correlations in the famous Fermi problem. This is an archetypal model to study micro-causalit…
Tuning non-Markovianity by spin-dynamics control
Salvatore Lorenzo, Francesco Plastina, Mauro Paternostro
We study the interplay between forgetful and memory-keeping evolution enforced on a two-level system by a multi-spin environment whose elements are coupled to local bosonic baths.…
Non-Markovianity, Loschmidt echo and criticality: a unified picture
Pinja Haikka, John Goold, Suzanne McEndoo +2
A simple relationship between recently proposed measures of non-Markovianity and the Loschmidt echo is established, holding for a two-level system (qubit) undergoing pure dephasing…
