Particle pairing causes subdiffusion of heavy particles in the imbalanced Hubbard model
Mirko Daumann, Thomas Dahm
The imbalanced Hubbard model features a transition between dynamic regimes depending on the mass ratio and coupling strength between two different particle species. A slowdown of t…

Anomalous Diffusion, Prethermalization, and Particle Binding in an Interacting Flat Band System
Mirko Daumann, Thomas Dahm
We study the broadening of initially localized wave packets in a quasi one-dimensional diamond ladder with interacting, spinless fermions. The lattice possesses a flat band causing…
