Abstract
By combining surprising new results from a full polarization analysis of nodal angle-resolved photoemission data from pristine and modulation-free Bi2Sr2CaCu2O{8+delta} with structural information from LEED and ab initio, one-step photoemission simulations, we prove that the shadow Fermi surface in these systems has structural origin, being due to orthorhombic distortions from tetragonal symmetry. Consequently, one of the longest standing open issues in the fermiology of these widely studied systems finally meets its resolution.
