Surface Dead Layer for Quasiparticles Near a Mott Transition
Surface Dead Layer for Quasiparticles Near a Mott Transition
Electron quasiparticles are progressively weakened by correlations upon approaching a continuos Mott metal-insulator transition in a bulk solid. We show that corresponding to the bulk weakening, a dead layer forms below the surface of the solid, where quasiparticles are exponentially suppressed. The surface dead layer depth is a bulk property …
