"New approaches in time-resolved ARPES"


ven 02/10/2018 - 10:30 - Aula Rossa, Dipartimento di Fisica



In this talk I will discuss recent results obtained in time and angle-resolved photoemission spectroscopy (ARPES) on quantum materials, utilizing ultrafast laser-based sources generating ultraviolet photons in the 6-40 eV range, with 190 fs and 20 mev time and energy resolutions, respectively. On the high-temperature superconducting cuprates, we obtained evidence for the collapse of superconductivity via ultrafast quenching of phase coherence [1] as well as of the vanishing of the pseudogap via quenching of the spin-correlation length. We also developed a novel approach for the direct determination of mode-projected electron-phonon coupling in the time-domain, with unprecedented sensitivity, and demonstrate its application to the case of graphite and its Dirac-like dispersion.
