Quasisymmetry Enriched Gapless Criticality at Chern Insulator Transitions
Jiayu Li, Feng-Ren Fan, Wang Yao
In continuous topological phase transitions (CTPTs), the low-energy physics is governed by gap-closing subspaces, where approximate "higher" symmetries, termed quasisymmetries, may…
Topological domain-wall states from Umklapp scattering in twisted bilayer graphene
Juncheng Li, Cong Chen, Wang Yao
Twistronics, harnessing interlayer rotation to tailor electronic states in van der Waals materials, has predominantly focused on small-angle regime. Here, we unveil the pivotal rol…
Observation of Cavity-Mediated Nonlinear Landau Fan and Modified Landau Level Degeneracy in Graphene Quantum Transport
Hongxia Xue, Hsun-Chi Chan, Zuzhang Lin +9
Recent studies on cavity-coupled two-dimensional electron gas demonstrate that vacuum-field engineering can tailor electronic transport properties of materials. By achieving ultra-…
Emergent Kagome lattice and non-Abelian lattice gauge field of biexcitons in t-MoTe
Haochen Wang, Wang Yao
Non-Abelian gauge fields, characterized by their non-commutative symmetry groups, shape physical laws from the Standard Model to emergent topological matter for quantum computation…
Spinless topological chirality from Umklapp scattering in twisted 3D structures
Cong Chen, Xu-Tao Zeng, Wang Yao
Spinless systems exhibit unique topological characteristics compared to spinful ones, stemming from their distinct algebra. Without chiral interactions typically linked to spin, an…
