Exotic States in the Dynamical Casimir Effect
Giuliano Benenti, Stefano Siccardi, Giuliano Strini
We consider the interaction of a qubit with a single mode of the quantized electromagnetic field and show that, in the ultrastrong coupling regime and when the qubit-field interact…
Dynamical Casimir-Polder interaction between an atom and surface plasmons
Harald R. Haakh, Carsten Henkel, Salvatore Spagnolo +2
We investigate the time-dependent Casimir-Polder potential of a polarizable two-level atom placed near a surface of arbitrary material, after a sudden change in the parameters of t…
Quantum probes for the spectral properties of a classical environment
Claudia Benedetti, Fabrizio Buscemi, Paolo Bordone +1
We address the use of simple quantum probes for the spectral characterization of classical noisy environments. In our scheme a qubit interacts with a classical stochastic field des…
Characterizing the non-classicality of mesoscopic optical twin-beam states
Alessia Allevi, Marco Lamperti, Maria Bondani +4
We present a robust tool to analyze nonclassical properties of multimode twin-beam states in the mesoscopic photon-number domain. The measurements are performed by direct detection…
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…
Translationally invariant conservation laws of local Lindblad equations
Marko Znidaric, Giuliano Benenti, Giulio Casati
We study the conditions under which one can conserve local translationally invariant operators by local translationally invariant Lindblad equations in one-dimensional rings of spi…
