Quantum theory of longitudinal-transverse polaritons in nonlocal thin films
Christopher R. Gubbin, Simone De Liberato
When mid-infrared light interacts with nanoscale polar dielectric structures optical phonon propagation cannot be ignored, leading to a rich nonlocal phenomenology which we have on…
Nonlocal Scattering Matrix Description of Anisotropic Polar Heterostructures
Christopher R. Gubbin, Simone De Liberato
Polar dielectrics are a promising platform for mid-infrared nanophotonics, allowing for nanoscale electromagnetic energy confinement in oscillations of the crystal lattice. We rece…
Hybrid Longitudinal-Transverse Phonon Polaritons
Christopher R. Gubbin, Rodrigo Berté, Michael A. Meeker +6
We demonstrate how to exploit long-cell polytypes of silicon carbide to achieve strong coupling between transverse phonon polaritons and zone folded longitudinal optical phonons. T…
Second harmonic generation from strongly coupled localized and propagating phonon-polariton modes
Ilya Razdolski, Nikolai Christian Passler, Christopher R. Gubbin +8
We experimentally investigate second harmonic generation from strongly coupled localized and propagative phonon polariton modes in arrays of silicon carbide nanopillars. Our result…
Open quantum systems with local and collective incoherent processes: Efficient numerical simulation using permutational invariance
Nathan Shammah, Shahnawaz Ahmed, Neill Lambert +2
The permutational invariance of identical two-level systems allows for an exponential reduction in the computational resources required to study the Lindblad dynamics of coupled sp…
Resonant intersubband polariton-LO phonon scattering in an optically pumped polaritonic device
J-M. Manceau, L. Tran, G. Biasiol +6
We report experimental evidence of longitudinal optical (LO) phonon-intersubband polariton scattering processes under resonant injection of light. The scattering process is resonan…
