Emergent Causality and the N-photon Scattering Matrix in Waveguide QED
Eduardo Sánchez-Burillo, Andrea Cadarso, Luis Martín-Moreno +2
In this work we discuss the emergence of approximate causality in a general setup from waveguide QED -i.e. a one-dimensional propagating field interacting with a scatterer. We prov…
Full two-photon downconversion of just a single photon
E. Sánchez-Burillo, L. Martín-Moreno, J. J. García-Ripoll +1
We demonstrate, both numerically and analytically, that it is possible to generate two photons from one and only one photon. We characterize the output two photon field and make ou…
Scattering in the ultrastrong regime: nonlinear optics with one photon
Eduardo Sánchez-Burillo, David Zueco, Juanjo García-Ripoll +1
The scattering of a flying photon by a two-level system ultrastrongly coupled to a one-dimensional photonic waveguide is studied numerically. The photonic medium is modeled as an a…
