研究目的
Investigating the formation of stable orthogonally polarised domains in high-density polariton solitons propagating in a semiconductor microcavity wire due to spin dependent polariton-polariton interactions and pump-induced imbalance of polariton spin populations.
研究成果
The formation of polariton spin domains within high-density wavepackets evolving into conservative soliton(s) in a quasi-1D system was demonstrated. The polarisation precession during propagation is caused by an effective magnetic field due to splittings between linearly polarised polariton components at low excitation. With increasing polariton density, an extra pump-induced magnetic field due to anisotropy in the spin-dependent polariton-polariton interactions results in formation of spatially separated polarisation domains.
研究不足
The study is limited to quasi-1D systems and specific conditions of polariton densities and excitation powers. The complex spatio-temporal polarisation dynamics at high polariton densities may require further investigation for full understanding.
