2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/122181We demonstrate how dynamic correlations of heavy-hole and light-hole excitons in semiconductor quantum wells may be investigated by two dimensional correlation spectroscopy (2DCS). The coherent response to three femtosecond optical pulses is predicted to yield cross (off-diagonal) peaks that contain direct signatures of many-body two-exciton correlations. Signals generated at various phase-matching directions are compared.27pages,13 figures, accepted for publication in Physical Review BMesoscale and Nanoscale Physicstext
