This study demonstrates a novel quantum mechanism linking supersolidity and magnetism in ultracold atomic systems with tunable gauge fields. By utilizing magnetic lanthanide atoms in an optical lattice, the research achieves a robust lattice supersolid regime where density modulations induce specific ferromagnetic or ferrimagnetic flux patterns. These findings advance our understanding of strongly correlated matter by bridging two distinct regimes through experimentally accessible quantum effects.
Flux Magnetism in a Strongly Interacting Dipolar Lattice Supersolid under Tunable Gauge Fields
arXiv:2509.05058v3 Announce Type: replace-cross Abstract: Supersolidity and magnetism are fundamental phenomena characterizing strongly correlated matter. Here we unveil a mechanism that directly connects these two regimes and can be experimentally accessed in ultracold atomic systems. Specifically, we exploit the distinctive properties of magnetic lanthanide atoms trapped in a one-dimensional antimagic wavelength optical lattice. This platform enables a realistic implementation of a triangular Bose-Hubbard ladder featuring two key ingredients: strong long-range interactions and tunable gauge fields. Owing to these properties, our numerical analysis reveals a robust lattice supersolid regime with finite fluxes in each triangular plaquette. Remarkably, we show that the density modulation of the supersolid phase and a finite gauge field induce magnetic ordering of the fluxes, forming ferromagnetic and ferrimagnetic patterns. Our results thus reveal a quantum effect that bridges supersolidity and magnetism.
