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…
