Time- and angle-resolved photoemission of quantum materials

Wednesday, October 23, 2019 - 3:00pm to 4:00pm

SLAC, 901-108 A&B Redtail Hawk Conference Rooms

Speaker: Fabio Boschini, UBC

Program Description:
The extension of angle-resolved photoemission spectroscopy into the time domain (TR-ARPES) has offered the unique opportunity to access low-energy electronic properties with momentum, energy and time resolution.
I will present recent results about the filling of the superconducting gap [1] and the electron-boson band-dispersion renormalization in hole-doped cuprates, as well as the intimate relation between the pseudogap and the short-range antiferromagnetic correlations in electron-doped cuprates [2].
Finally, I will propose a way to redefine the paradigms of the TR-APRES analysis and access the mode-projected electron-phonon matrix element in graphite in an ultrafast fashion [3].
