Parameswaran, Hong Yao, B. Andrei Bernevig, and Haoyu Hu We establish twisted ${\mathrm{SnSe}}_{2}$ as a tunable platform for simulating dimension-dependent correlated physics, distinct from conventional K-valley moiré systems. By constructing interacting Wannier models, we show that the stacking configuration dictates the effective lattice geometry. In A… [Phys. Rev. B 114, L051113] Published Fri Jul 31, 2026
