Abstract :
Summary form only given. The microscopic many-body theory applied to the time-resolved vectorial polarization state of the FWM signal documents two-exciton correlations. Under our experimental conditions, the biexciton dephasing rate is found to be much less than twice the exciton dephasing rate.
