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…

A solvable model for strongly interacting nonequilibrium excitons
Zhenhao Song, Tessa Cookmeyer, Leon Balents
We study the driven-dissipative Bose-Hubbard model with all-to-all hopping and subject to incoherent pumping and decay, as is naturally probed in several recent experiments on exci…
