We have posted a new paper regarding imaging pseudospin dynamics in graphene. Working at the low excitation fluences enabled by our unique tr-ARPES instrument, we are able to vary the relative importance of electron-electron and electron-phonon scattering on the dynamics and also momentum-resolve the nascent photoexcited electrons before they relax. These are very challenging measurements due the very short carrier lifetimes in graphene and the need to resolve fine momentum-space features of the distributions.
