Title: Extraction of the electron self-energy from angle-resolved photoemission data: Application to Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+x}

Abstract

The self-energy {Sigma}({bold k},{omega}), the fundamental function that describes the effects of many-body interactions on an electron in a solid, is usually difficult to obtain directly from experimental data. In this paper we show that by making certain reasonable assumptions, the self-energy can be directly determined from angle-resolved photoemission data. We demonstrate this method on data for the high-temperature superconductor Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+x} in the normal, superconducting, and pseudogap phases. {copyright} {ital 1999} {ital The American Physical Society}
