Abstract

We study the coherent light-matter interactions associated with excitons, biexcitons, and many-body effects in GaAs quantum wells. For most polarization configurations the phase-resolved two-dimensional Fourier-transform (2DFT) spectra are dominated by excitonic features, where their strength and dispersive line shapes are due to many-body interactions. Cross-linear excitation suppresses many-body interactions, changing the line shape and strength of the 2DFT features.
