Quasi-particle excitations at Mott-metal interfaces — •Jan Verlage1, Friedemann Queisser2,3, Peter Kratzer1, and Ralf Schützhold2,3 — 1Fakultät für Physik, Universität Duisburg-Essen — 2Institut für Theoretische Physik, Helmholtz-Zentrum Dresden-Rossendorf — 3Institut für Theoretische Physik, Technische Universität Dresden
We investigate excitations at the interface between a metallic bulk and a strongly correlated Mott insulator.
Employing a hierarchy of correlations we identify effective
quasi-particle and hole excitations in the heterostructure.
To leading order in the hierarchy, the modes satisfy an effective two-component evolution equation.
This allows the investigation of evanescent modes at the interface and tunneling through a Mott insulating layer.
