Description of ultrastrong light-matter interaction through coupled harmonic oscillator models and their connection with cavity-QED Hamiltonians
Unai Muniain, Javier Aizpurua, Rainer Hillenbrand +2
Classical coupled harmonic oscillator models are capable of describing the optical and infrared response of nanophotonic systems where a cavity photon couples to dipolar matter exc…
Waveguide QED in the Dipole Gauge
Sergi Terradas-Briansó, Luis Martín-Moreno, David Zueco
In recent studies on ultrastrong coupling between matter and light in cavities, the significance of gauge choice when employing the widely-used two-level approximation has been hig…
Finding discrete symmetry groups via Machine Learning
Pablo Calvo-Barlés, Sergio G. Rodrigo, Eduardo Sánchez-Burillo +1
We introduce a machine-learning approach (denoted Symmetry Seeker Neural Network) capable of automatically discovering discrete symmetry groups in physical systems. This method ide…
Spin-momentum locking breakdown on plasmonic metasurfaces
Fernando Lorén, Cyriaque Genet, Luis Martín-Moreno
We present a scattering formalism to analyze the spin-momentum locking in structured holey plasmonic metasurfaces. It is valid for any unit cell for arbitrary position and orientat…
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…
