Symmetry-enabled tunable square-lattice Hubbard models in -valley moiré bilayers
Rui Shi, Kejie Bao, Huan Wang +1
Square-lattice moiré systems provide a promising route for quantum simulation of Hubbard physics, yet electrically tunable realizations of the hopping ratio have so far been…

Moiré Ferroelectricity-Driven Band Engineering in Twisted Square Bilayers
Kejie Bao, Rui Shi, Huan Wang +2
We develop the moiré band theory for M-valley twisted square homobilayers with layer groups - and -, and propose candidate material realizations. We show that moiré…
