Imaging electronic energy transport and many-body interactions in spatiotemporal microscopy

I will describe our recent efforts to directly image and control electronic energy transport in van der Waals semiconductors using ultrafast spatiotemporally-resolved optical microscopy. I will focus on how we selectively image, understand and control interactions between different excitations to form hybrid quasiparticles that exhibit remarkable transport properties, including wavelike (scatter-free) energy flow at room temperature.
