Non-reciprocal few-photon devices based on chiral waveguide-emitter couplings
C. Gonzalez-Ballestero, Esteban Moreno, F. J. Garcia-Vidal +1
We demonstrate the possibility of designing efficient, non reciprocal few-photon devices by exploiting the chiral coupling between two waveguide modes and a single quantum emitter.…
When polarons meet polaritons: Exciton-vibration interactions in organic molecules strongly coupled to confined light fields
Ning Wu, Johannes Feist, Francisco J. Garcia-Vidal
We present a microscopic semi-analytical theory for the description of organic molecules interacting strongly with a cavity mode. Exciton-vibration coupling within the molecule and…
Exploiting vibrational strong coupling to make an optical parametric oscillator out of a Raman laser
Javier del Pino, Francisco J. Garcia-Vidal, Johannes Feist
When the collective coupling of the rovibrational states in organic molecules and confined electromagnetic modes is sufficiently strong, the system enters into vibrational strong c…
Uncoupled dark states can inherit polaritonic properties
C. Gonzalez-Ballestero, J. Feist, E. Gonzalo-Badia +2
When a collection of quantum emitters interacts with an electromagnetic field, the whole system can enter into the collective strong coupling regime in which hybrid light-matter st…
Suppressing photochemical reactions with quantized light fields
Javier Galego, Francisco J. Garcia-Vidal, Johannes Feist
Photoisomerization, i.e., a change of molecular structure after absorption of a photon, is one of the most fundamental photochemical processes. It can perform desirable functionali…
Plasmon-Exciton-Polariton Lasing
Mohammad Ramezani, Alexei Halpin, Antonio I. Fernández-Domínguez +4
Metallic nanostructures provide a toolkit for the generation of coherent light below the diffraction limit. Plasmonic based lasing relies on the population inversion of emitters (s…
Transformation Optics Approach to Plasmon-Exciton Strong Coupling in Nanocavities
Rui-Qi Li, D. Hernangómez-Pérez, F. J. García-Vidal +1
We investigate the conditions yielding plasmon-exciton strong coupling at the single emitter level in the gap between two metal nanoparticles. A quasi-analytical transformation opt…
