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…
Mott insulators in moiré transition metal dichalcogenides at fractional fillings: Slave-rotor mean-field theory
Zhenhao Song, Urban F. P. Seifert, Zhu-Xi Luo +1
In this work, we study a slave-rotor mean-field theory of an extended Hubbard model, applicable to transition metal dichalcogenide moiré systems, that captures both the formation o…
