“…We then describe the reference measurement used to benchmark our experimental setup. Based on a simple model, we estimate the exciton-exciton interaction strength in a neutral quantum well to amount to 13 +18 −9 µeV µm 2 , consistent with other reports [4,5,15,16,18,[41][42][43][44]. We finally present a detailed study of the evolution of the polariton coherence time around fractional filling factors.…”

“…Following the estimates given in Ref. 26, we found that in our system the additional blueshift is about 2 and 3 times smaller than that involved by the exciton-exciton interaction at CX = −2 meV and CX = +0.5 meV, respectively. Since the obtained values of α 2 /α 1 are small and have large relative errors, this effect would provide only a small correction to our results.…”

“…In particular, we do not consider the saturation of exciton transitions 10,26 that is significant at large negative CX . Phase-space filling leads to a reduction of exciton oscillator strength thus causing an additional blueshift with increasing occupation numbers, which lowers the threshold for each of the σ ± components of the field.…”

“…Здесь E x и E c -энергия излуча-тельной рекомбинации экситона и энергия фотонного резонанса в микрорезонаторе соответственно. В нулевом магнитном поле в спектре ФЛ видна единственная линия, которая имеет линейную поляризацию ρ l > 90%, что является типичным для ФЛ конденсата в пла-нарных структурах или МС и объясняется влияни-ем поляритон-поляритонного взаимодействия, так как энергия конденсата поляритонов в этом случае ми-нимальна [4]. Степень линейной поляризация быстро уменьшается с ростом магнитного поля B и в полях B > 2.5 Tл обращается в нуль, как это видно из рис.…”
