摘要：

We present a self-consistent treatment of the electron-hole correlations in optically excited quantum wires within the ladder approximation and using a contact potential interaction. The limitation of the ladder approximation to the excitonic low-density region is largely overcome by the introduction of higher-order correlations through self-consistency. We show the relevance of these correlations in the low-temperature emission, even for high density, when a large gain replaces the excitonic absorption.
