| contents | Supersolidity and magnetism are fundamental phenomena characterizing strongly correlated states of matter. Here, we unveil a mechanism that establishes a direct connection between these quantum regimes and can be experimentally accessed in ultracold atomic systems. Specifically, we exploit the distinctive properties of ultracold magnetic lanthanide atoms trapped in a one dimensional anti-magic wavelength optical lattice. This allows us to design a realistic implementation of a triangular Bose-Hubbard ladder featuring two essential ingredients: strong long-range interactions and tunable gauge fields. Thanks to these unconventional properties, our numerical analysis highlights that, among the others, a robust lattice supersolid regime with finite fluxes in each triangular plaquette occurs. Remarkably, we show that the specific density distribution of the supersolid phase leads to the magnetic ordering of fluxes, which can form ferrimagnetic and ferromagnetic structures. Our results thus discover a fascinating quantum mechanical effect that bridges supersolidity and magnetism. |
