Generalized spin-boson models with non-normalizable form factors
Davide Lonigro
Generalized spin-boson (GSB) models describe the interaction between a quantum mechanical system and a structured boson environment, mediated by a family of coupling functions know…
Quantum magnetic billiards: boundary conditions and gauge transformations
Giuliano Angelone, Paolo Facchi, Davide Lonigro
We study admissible boundary conditions for a charged quantum particle in a two-dimensional region subjected to an external magnetic field, i.e. a quantum magnetic billiard. After…
The self-energy of Friedrichs-Lee models and its application to bound states and resonances
Davide Lonigro
A system composed of two-level systems interacting with a single excitation of a one-dimensional boson field with continuous spectrum, described by a Friedrichs (or Friedrichs-Lee)…
Quantum non-Markovianity elusive to interventions
Daniel Burgarth, Paolo Facchi, Davide Lonigro +1
The non-Markovian nature of open quantum dynamics lies in the structure of the multitime correlations, which are accessible by means of interventions. Here, by examining multitime…
Quantum controllability on graph-like manifolds through magnetic potentials and boundary conditions
Aitor Balmaseda, Davide Lonigro, Juan Manuel Pérez-Pardo
We investigate the controllability of an infinite-dimensional quantum system: a quantum particle confined on a Thick Quantum Graph, a generalisation of Quantum Graphs whose edges a…
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…
