In article number 1800171 , Christopher L. Smallwood and Steven T. Cundiff introduce a multidimensional coherent spectroscopy (MDCS) probe of the dynamics of excitons in an asymmetric In 0.05 Ga 0.95 As/GaAs double quantum well. Spectral information here is plotted as a correlation between the frequency of a first‐order optical excitation interaction ( ω τ ) and a third‐order emission interaction ( ω t ) at various intermediate‐state mixing times (T), providing a window into a semiconductor's inhomogeneity, many‐body interactions, and coherent coupling dynamics at femtosecond timescales.
