Using 2D ultrafast spectroscopy to measure interactions between same spin and opposite spin Exciton-Polaritons in a Gallium Arsenide quantum well.

About the presenter

Matthew Berkman is an Honours student working with CI Jeff Davis at Swinburne. His project is focusing on measuring polariton interactions with multidimensional coherent spectroscopy. Specifically, he’s quantifying the complex valued interaction strength between polaritons (in GaAs system) as a function of exciton fraction and for same and opposite spin polaritons
