The coherent optical response is important from the perspective of applications in quantum information. Two-dimensional coherent spectroscopy (2DCS) is a powerful technique to study such properties in a variety of systems. Such experiments are typically performed in relatively low-excitation regime, particularly due to theoretical limitations of interpreting the data for high-intensity excitation. Dr. Rohan Singh and coworkers have demonstrated technique to perform exact calculations of 2D spectra even in the high-intensity regime. They have used these simulations to model experiments performed on semiconductor nanostructures, both in their group and previously reported results. These results are significant for the community of researchers performing spectroscopy with intense light.
