Coupled-wire descriptions of unconventional quantum states in twisted nanostructures
Chen-Hsuan Hsu, Anna Ohorodnyk
Coupled-wire description has been developed as a powerful framework for providing bosonic descriptions of strongly correlated quantum matter, with early applications to systems suc…
Versatile multi-q antiferromagnetic charge order in correlated vdW metals
Y. Fujisawa, P. Wu, R. Okuma +13
Following the discovery of graphene, interest in van der Waals (vdW) materials has surged; however, advancing physics beyond graphene requires quantum vdW materials platforms that…
Tunable Competing Electronic Orders in Double Quantum Spin Hall Superlattices
Yi-Chun Hung, Chen-Hsuan Hsu, Arun Bansil
Competing superconducting (SC) and density-wave orders are of key importance in generating unconventional superconductivity and emergent electronic responses. Quasi-one-dimensional…
Emergent topological magnetism in Hund's excitonic insulator
R. Okuma, K. Yamagami, Y. Fujisawa +14
Analogous to the charged electron-electron pair condensation in superconductors, an excitonic insulator (EI) represents Fermi surface instability due to spontaneous formation and c…
