Superconducting properties of the three-dimensional Hofstadter-Hubbard model below the critical flux for Weyl points
Pierpaolo Fontana, Luca Lepori, Andrea Trombettoni
The three-dimensional Hofstadter model exhibits a critical rational flux at which Weyl points emerge in the single-particle spectrum. We study the superconducting regime of the mod…

Crossover and Critical Behavior in the Layered XY Model
Roman Kracht, Andrea Trombettoni, Ilaria Maccari +1
Motivated by the interplay between 2D and 3D scaling signatures observed in unconventional layered superconductors, we present a systematic Monte Carlo study of the three-dimension…
