Su-Schrieffer-Heeger-Hubbard model at quarter filling: effects of magnetic field and non-local interactions
David Mikhail, Stephan Rachel
The interplay and competition of topology and electron-electron interactions have fascinated researchers since the discovery of topological insulators. The Su-Schrieffer-Heeger-Hub…

Probing Hilbert space fragmentation and the block inverse participation ratio
Philipp Frey, David Mikhail, Stephan Rachel +1
We consider a family of quantum many-body Hamiltonians that show exact Hilbert space fragmentation in certain limits. The question arises whether fragmentation has implications for…
