Stationary excitation waves and multimerization in arrays of quantum emitters
Davide Lonigro, Paolo Facchi, Saverio Pascazio +2
We explore the features of an equally-spaced array of two-level quantum emitters, that can be either natural atoms (or molecules) or artificial atoms, coupled to a field with a sin…
Photon-emitter dressed states in a closed waveguide
Davide Lonigro, Paolo Facchi, Andrew D. Greentree +3
We study a system made up of one or two two-level quantum emitters, coupled to a single transverse mode of a closed waveguide, in which photon wavenumbers and frequencies are discr…
Hidden non-Markovianity in open quantum systems
Daniel Burgarth, Paolo Facchi, Marilena Ligabò +1
We show that non-Markovian open quantum systems can exhibit exact Markovian dynamics up to an arbitrarily long time; the non-Markovianity of such systems is thus perfectly "hidden"…
Spectral properties of the singular Friedrichs-Lee Hamiltonian
Paolo Facchi, Marilena Ligabò, Davide Lonigro
We show that the Friedrichs-Lee model, which describes the one-excitation sector of a two-level atom interacting with a structured boson field, can be generalized to singular atom-…
Bound states in the continuum for an array of quantum emitters
Paolo Facchi, Davide Lonigro, Saverio Pascazio +2
We study the existence of bound states in the continuum for a system of n two-level quantum emitters, coupled with a one-dimensional boson field, in which a single excitation is sh…
