Microscopic theory of polariton-polariton interactions
Esben R. Christensen, Arturo Camacho-Guardian, Ovidiu Cotlet +4
We develop a comprehensive theoretical model for the interaction strength between a pair of exciton-polaritons in microcavity devices. Ab initio numerical calculations for dipolar…
Topological Frenkel Exciton-Polaritons in One-Dimensional Lattices of Strongly Coupled Cavities
J. Andrés Rojas-Sánchez, Yesenia A. García Jomaso, Brenda Vargas +5
Frenkel polaritons, hybrid light-matter quasiparticles, offer promises for the designing of new opto-electronic devices. However, their technological implementations are hindered b…
The Fate of the Upper Polariton: Breakdown of the Quasiparticle Picture in the Continuum
Yesenia A. García Jomaso, Brenda Vargas, David Ley Dominguez +4
Organic polaritons resulting from the strong hybridisation between photons and matter excitations have arisen as a suitable platform to device light-matter technological interfaces…
Optical non-linearities and spontaneous translational symmetry breaking in driven-dissipative moiré exciton-polaritons
A. Camacho-Guardian, N. R. Cooper
Moiré lattices formed from semiconductor bilayers host tightly localised excitons that can simultaneously couple strongly to light and possess large electric dipole moments. This f…
Light-induced topological superconductivity in transition metal dichalcogenide monolayers
Aleksi Julku, Jami J. Kinnunen, Arturo Camacho-Guardian +1
Monolayer transition metal dichalcogenides (TMDs) host deeply bound excitons interacting with itinerant electrons, and as such they represent an exciting new quantum many-body Bose…
Life and death of the Bose polaron
Magnus G. Skou, Kristian Knakkergaard Nielsen, Thomas G. Skov +6
Spectroscopic and interferometric measurements complement each other in extracting the fundamental properties of quantum many-body systems. While spectroscopy provides precise meas…
Strong photon interactions from weakly interacting particles
Arturo Camacho-Guardian, Miguel Bastarrachea-Magnani, Thomas Pohl +1
The hybridization of light and matter excitations in the form of polaritons has enabled major advances in understanding and controlling optical nonlinearities. Entering the quantum…
