We determine experimentally the spinor interaction constants of lower polaritons α1 and α2 using a resonant pump-probe spectroscopy with a spectrally narrow pump pulse. Our experimental findings are analyzed with the Bogoliubov-type theory and a mean-field two channel model based on the lower polariton and biexciton basis. We find an enhancement of the attractive interaction and a dissipative non-linearity of lower polaritons with anti-parallel spins in the vicinity of the biexciton resonance when the energy of two lower polaritons approaches energetically that of the biexciton. These observations are consistent with the existence of a scattering resonance between lower polaritons and biexcitons (polaritonic Feshbach resonance).

“…No additional assumptions for the effective polariton-polariton interaction are needed, which is directly included in our theory via the frequency dependent and complex exciton-exciton scattering matrices. 10 Our theoretical analysis incorporates: (i) the well-established microscopic many-particle theory for the optically-induced QW polarization dynamics based on the dynamics-controlled truncation (DCT) formalism 26,27 , and (ii) the self-consistent coupling of this dynamics to the dynamics of the optical fields in the cavity modes 10,28,29 including all vectorial polarization state channels. The theory consistently includes all coherent third order (χ (3) ) nonlinearities and the resulting equations of motion are solved in a self-consistent fashion in the optical fields which includes a certain class of higherorder nonlinearities.…”

Based on a microscopic many-particle theory we investigate the influence of excitonic correlations on the vectorial polarization state characteristics of the parametric amplification of polaritons in semiconductor microcavities. We study a microcavity with perfect in-plane isotropy. A linear stability analysis of the cavity polariton dynamics shows that in the co-linear (TE-TE or TM-TM) pump-probe polarization state configuration, excitonic correlations diminish the parametric scattering process whereas it is enhanced by excitonic correlations in the cross-linear (TE-TM or TM-TE) configuration. Without any free parameters, our microscopic theory gives a quantitative understanding how many-particle effects can lead to a rotation or change of the outgoing (amplified) probe signal's vectorial polarization state relative to the incoming one's.

“…Recently a number of nonlinear self-localisation phenomena with light-matter wave packets, cavity polaritons, in strongly-coupled planar quantum well semiconductor microcavities 21 have been demonstrated such as bright polariton solitons 22 , superfluidity 23,24 , pattern formation 25,26 , vortices 27,30 . Here we show that similar nonlinear selfconfinement mechanism takes place when a light-matter wave polariton soliton, rather than an optical soliton, propagates in a microcavity wire.…”

Coupled spatial multimode solitons in microcavity wires

A modal expansion approach is developed and employed to investigate and elucidate the nonlinear mechanism behind the multistability and formation of coupled multi-mode polariton solitons in microcavity wires. With pump switched on and realistic dissipation parameters, truncating the expansion up to the second-order wire mode, our model predicts two distinct coupled soliton branches: stable and ustable. Modulational stability of the homogeneous solution and soliton branches stability are studied. Our simplified 1D model is in remarkably good agreement with the full 2D mean-field Gross-Pitaevskii model, reproducing correctly the soliton existence domain upon variation of pump amplitude and the onset of multistability.
