Fermi surface, pseudogaps and dynamical stripes in La2-xSrxCuO4

Doping dependence of the electronic structure of La${}_{2-x}$Sr${}_x$CuO${}_4$ (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.
