One- and two-photon scattering from generalized v -type atoms 2016 Access copy available to the general public Unrestricted The one- and two-photon scattering matrix S is obtained analytically for a one-dimensional waveguide and a pointlike scatterer with N excited levels (generalized V-type atom). We argue that the two-photon scattering matrix contains sufficient information to distinguish between different level structures which are equivalent for single-photon scattering, such as a V atom with N=2 excited levels and two two-level systems. In particular, we show that the scattering with the V-type atom exhibits a destructive interference effect leading to two-photon coupled-resonator-induced transparency, where the nonlinear part of the two-photon scattering matrix vanishes when each incident photon fulfills a single-photon condition for transparency. info:eu-repo/grantAgreement/ES/MINECO/MAT2014-53432-C5 info:eu-repo/grantAgreement/ES/MINECO/FIS2012-33022 info:eu-repo/grantAgreement/EC/FP7/258191/EU/Participative Research labOratory for Multimedia and Multilingual Information Systems Evaluation/PROMISE info:eu-repo/grantAgreement/ES/DGA/FENOL-GROUP info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.482 2016 Atomic and Molecular Physics, and Optics 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-9273-8165 Martín-Moreno, L.
