Enhanced Electron Reflectionat Mott-Insulator Interfaces
Jan Verlage, Peter Kratzer
The Klein paradox describes an incoming electron being scattered at a supercritical barrier to create electron-positron pairs, a phenomenon widely discussed in textbooks. While dem…

Bound States at Semiconductor -- Mott Insulator Interfaces
Jan Verlage, Peter Kratzer
Utilizing the hierarchy of correlations in the context of a Fermi-Hubbard model, we deduce the presence of quasi-particle bound states at the interface between a Mott insulator and…

Transmission through multiple Mott insulator - semiconductor wells
Jan Verlage, Peter Kratzer
Weakly and strongly interacting quantum many-body systems, namely semiconductors and Mott insulators, are combined into a layered heterostructure. Via the hierarchy of correlations…
