We develop a theoretical model for the interaction strength between a pair of exciton-polaritons with finite and parallel static electric-dipole moments. In stark contrast to simple perturbative arguments predicting the interaction to be reduced due to the hybridisation with cavity photons, we find that the strong coupling to a cavity mode leads to a drastic enhancement of the polariton interactions as compared to bare excitons. This enhancement is caused by the small polariton mass due to its…

Enhanced Interactions between Dipolar Polaritons.

A substantial increase in interaction strength between dipolar polaritons is reported as the size of the dipole is increased by tuning the applied gate voltage, indicating that dipolar Polaritons could constitute an important step towards a demonstration of the polariton blockade effect, and thereby to form the building blocks of many-body states of light.

Polariton interactions in microcavities with atomically thin semiconductor layers

We investigate the interactions between exciton-polaritons in N two-dimensional semiconductor layers embedded in a planar microcavity. In the limit of low-energy and low-momentum scattering, where we

Strongly interacting dipolar-polaritons

A system of optically guided, electrically polarized exciton-polaritons (“dipolaritons”) that displays up to 200-fold enhancement of the polariton- polariton interaction strength compared to unpolarized polaritons is demonstrated.

Microscopic calculation of polariton scattering in semiconductor microcavities

Recent experiments in exciton-polariton systems have provided high-precision measurements of the value of the polariton-polariton interaction constant, which is a key parameter that governs the

Polariton-polariton interaction beyond the Born approximation: A toy model study

We theoretically investigate the polariton-polariton interaction in microcavities beyond the commonly used Born approximation (i.e., mean field), by adopting a toy model with a contact interaction to

Attractive and Repulsive Exciton-Polariton Interactions Mediated by an Electron Gas.

This work explores the interactions between exciton-polaritons and trions in a two-dimensional semiconductor injected with an electron gas inside a microcavity and shows that particle-hole excitations in the electron gas mediate an attractive interaction between the polaritons.

Towards polariton blockade of confined exciton–polaritons

Evidence of quantum correlations between polaritons spatially confined in a fibre cavity is reported, an essential step towards the realization of strongly interacting photonic systems.

Mediated Interactions and Photon Bound States in an Exciton-Polariton Mixture.

Using a theory that takes into account nonperturbative correlations between the excitons as well as strong light-matter coupling, it is demonstrated the high tunability of an effective interaction between quasiparticles formed by minority component polaritons interacting with a Bose-Einstein condensate (BEC) of a majority component polarites.

Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation

Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor) provide a solid-state platform for studies of non-equilibrium quantum systems with a spontaneous macroscopic

Emergence of quantum correlations from interacting fibre-cavity polaritons

This work reports on the emergence of quantum correlations in laser light transmitted through a fibre-cavity polariton system, and observes a dispersive shape of the autocorrelation function around the polariton resonance that indicates the onset of this regime.
