Mgr. František Herman, PhD.:
Two-lifetime model for the cuprates reimagined

Abstract:
We propose a two-lifetime phenomenological model of the superconducting state of the cuprates, and we show that it explains several salient low-energy features of the measured angle-resolved photoemission spectroscopy (ARPES) spectra. The model enables discrimination between forward- and large-angle scattering and, in addition, gives access to the magnitude of the gap function away from the Fermi surface.

Note: I will try to do things in the simplest way possible. One can expect a lot of figures, maybe a bit of fun. Bring coffee, please, so you can enjoy it :). Highly recommended for all physics students.
