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…
Kibble-Zurek dynamics in the anisotropic Ising model of the Si(001) surface
Gernot Schaller, Friedemann Queisser, Seyedeh Parya Katoorani +8
As a simplified description of the non-equilibrium dynamics of buckled dimers on the Si(001) surface, we consider the anisotropic 2D Ising model and study the freezing of spatial c…
