Unconventional Self-Similar Hofstadter Superconductivity from Repulsive Interactions
Daniel Shaffer, Jian Wang, Luiz H. Santos
Fractal Hofstadter bands have become widely accessible with the advent of moiré superlattices, opening the door to studies of the effect of interactions in these systems. In this w…

Theory of Hofstadter Superconductors
Daniel Shaffer, Jian Wang, Luiz H. Santos
We study mean-field states resulting from the pairing of electrons in time-reversal broken fractal Hofstadter bands, which arise in two-dimensional lattices where the unit cell tra…
