Supermoiré Chern mosaic in helical trilayer WSe2
Zhenyu Wang, Mingjie Zhang, Hai Meng +19
Helically twisted multilayers offer access to moiré physics beyond the single-superlattice paradigm, yet their correlated and topological transport properties remain largely unexpl…
Transport Evidence for Wigner Crystals in Monolayer MoTe2
Mingjie Zhang, Zhenyu Wang, Yifan Jiang +7
The crystallization of charge carriers, dubbed the Wigner crystal, is anticipated at low densities in clean two-dimensional electronic systems (2DES). While there has been extensiv…
Pomeranchuk Effect and Tunable Quantum Phase Transitions in 3L-MoTe2/WSe2
Mingjie Zhang, Xuan Zhao, Kenji Watanabe +5
Many sought-after exotic states of matter are known to emerge close to quantum phase transitions, such as quantum spin liquids (QSL) and unconventional superconductivity. It is thu…
Tunable bilayer Hubbard model physics in twisted WSe2
Yang Xu, Kaifei Kang, Kenji Watanabe +3
Moiré materials with flat electronic bands provide a highly controllable quantum system for studies of strong-correlation physics and topology. In particular, angle-aligned heterob…
Abundance of correlated insulating states at fractional fillings of WSe/WS moiré superlattices
Yang Xu, Song Liu, Daniel A Rhodes +6
Quantum particles on a lattice with competing long-range interactions are ubiquitous in physics. Transition metal oxides, layered molecular crystals and trapped ion arrays are a fe…
