Emergent Gauge Flux in Mixed QED with Flavor Chemical Potential: Implications for Magnetized U(1) Dirac Spin Liquids
Chuang Chen, Urban F. P. Seifert, Kexin Feng +3
We design a lattice model of a "mixed" U(1) gauge field coupled to fermions with a flavor chemical potential and solve it with large-scale determinant quantum Monte Carlo simulatio…

Emergent magnetism and spin liquids in an extended Hubbard description of moiré bilayers
Zhenhao Song, Urban F. P. Seifert, Leon Balents +1
Motivated by twisted transition metal dichalcogenides (TMDs), we study an extended Hubbard model with both on-site and off-site repulsive interactions, in which Mott insulating sta…
