Interplay of local and global quantum geometry in the stability of flat-band superfluids
Kukka-Emilia Huhtinen, Matteo Dürrnagel, Valerio Peri +1
Quantum geometry strongly impacts physical properties in flat-band systems. We consider its role in bosonic condensation and superfluidity on flat bands, and show that the superflu…

Partial suppression of magnetism in the square lattice SU(3) Hubbard model
Samuel Bird, Sebastian Huber, Jannes Nys
The SU(N) Hubbard model is a natural extension of the SU(2) model. However, even the N=3 case remains poorly understood. We report a substantially new ground-state phase diagram of…
