Polarization-dependent angle-resolved photoemission data with submicron spatial resolution demonstrate such an electronic self-organization in NbSe3, a compound considered to be a paradigm of charge order. The new data indicate the emergence of a novel order, and reveal the one-dimensional (1D) physics hidden in a material which naively could be considered the most three dimensional of all columnar chalcogenides. The 1D physics is evidenced by a new selection rule¿in two polarizations we observe two strikingly different dispersions each closely resembling apparently contradicting results of previous studies of this material.application/pdfeng(c) American Physical Society, 2019Polarització (Física nuclear)FotoemissióPolarization (Nuclear physics)Photoemissioninfo:eu-repo/semantics/article6863402019-02-26info:eu-repo/semantics/openAccess
