Maths HEP Lunchtime Seminars: A Holographic Model of the Kondo Effect
31 May 2013 13:00 in CM101
Abstract The Kondo effect occurs in metals doped with magnetic impurities: in the ground state an electron binds to each impurity, leading to dramatic changes in the thermodynamic and transport properties of the metal. Although the single-impurity Kondo effect is considered a solved problem, the multi-impurity problem remains unsolved. Additionally, many questions remain about entanglement entropy and quantum quenches in Kondo systems. In this talk I will present a new model of the single-impurity Kondo effect based on holography, also known as gauge-gravity duality or the Anti-de Sitter/Conformal Field Theory (AdS/CFT) Correspondence, which may provide a new approach to open problems about Kondo systems.
