Fermi Surface, Pseudogaps and Dynamical Stripes in La2-x SR x CUO4

Doping dependence of the electronic structure of La2-x SR x CUO4 (LSCO) has been systematically studied in a series of photoemission measurements. The unusual spectral features in the underdoped regime are attributed to the formation of dynamical stripes and the opening of large and small pseudogaps.
