Emergent magnetism and spin liquids in an extended Hubbard description of moir'e bilayers
The study uses an extended Hubbard model to explore emergent magnetism and spin liquids in moiré transition metal dichalcogenides (TMDs). Simulations reveal a rich phase diagram where interaction strength ($U/t$) and filling factor ($ar{n}$) dictate whether the system forms magnetically ordered states, charge density waves, or quantum-disordered spin liquid phases. This suggests moiré TMDs are promising platforms for strongly interacting electron magnetism.
