Title: Electronic Structure of metallic stripes in the two-dimensional Hubbard model

Abstract: Using dynamical mean-field theory (DMFT) for the two-dimensional Hubbard model I will present results for populated domain walls in static striped phases. The calculated electronic structure shows a momentum dependent single-particle gap induced by stripe order and I will discuss in detail the observed unusual suppression of spectral weight along the Brillouin zone diagonal. The DMFT results will be compared to angle-resolved photoemission data of La_2-x-yNd_ySr_xCuO₄.
