Organizing Principles for Moiré Quantum Matter
Qiaoling Xu, Yifan Gao, Tao Zhang +16
Moiré flat bands in van der Waals bilayers are usually discussed through a small set of mechanisms associated with the and valleys of hexagonal crystals, and more recentl…

Engineering 2D square lattice Hubbard models in 90 twisted Ge/SnX (X=S, Se) moiré supperlattices
Qiaoling Xu, Ammon Fischer, Nicolas Tancogne-Dejean +6
Due to the large-period superlattices emerging in moire two-dimensional (2D) materials, electronic states in such systems exhibit low energy flat bands that can be used to simulate…

Quantum melting of generalized electron crystal in twisted bilayer MoSe2
Qi Jun Zong, Haolin Wang, Qi Zhang +12
Electrons can form an ordered solid crystal phase ascribed to the interplay between Coulomb repulsion and kinetic energy. Tuning these energy scales can drive a phase transition fr…
