Prof. Lede Xian (Tsientan Institute)
Moiré engineering has moved from a few canonical systems to a rapidly expanding materials space, but this expansion raises a basic question: given a parent monolayer, what low-energy quantum model will its moiré bands realize? We address this question by developing a valley–orbital–symmetry framework and applying it to more than 600 fully relaxed, commensurate twisted bilayers spanning four 2D...

Prof. Shengwei Jiang (Shanghai Jiao Tong University)
Two-dimensional semiconductor moiré superlattices provide a highly tunable platform for exploring emergent quantum states arising from the interplay of strong correlations and topology. In this talk, I will present our recent work on twisted trilayer MoTe2. By fabricating devices that incorporate both A-A bilayer and A-AB trilayer regions, and by combining low-temperature transport, magnetic...

Fengcheng Wu (Wuhan University)
Superconductivity has been widely observed in two-dimensional materials and their moiré superlattices. In this talk, I will present our theoretical studies of topological chiral superconductivity in semiconductor-based moiré systems. In twisted bilayer WSe₂, I will present a theoretical phase diagram describing the competition between an antiferromagnetic metal and a chiral d-wave...
