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…
