A Unified Categorical Description of Quantum Hall Hierarchy and Anyon Superconductivity
Donghae Seo, Taegon Lee, Gil Young Cho
We present a unified category-theoretic framework for quantum Hall hierarchy constructions and anyon superconductivity based on modular tensor categories over $\mathrm{Rep}(\mathrm…

Most two-dimensional bosonic topological orders forbid sign-problem-free quantum Monte Carlo: Nonpositive Gauss sum as an indicator
Donghae Seo, Minyoung You, Hee-Cheol Kim +1
Quantum Monte Carlo is a powerful tool for studying quantum many-body physics, yet its efficacy is often curtailed by the notorious sign problem. In this Letter, we introduce a nov…

Non-invertible duality and symmetry topological order of one-dimensional lattice models with spatially modulated symmetry
Donghae Seo, Gil Young Cho, Robert-Jan Slager
We investigate the interplay between self-duality and spatially modulated symmetry of generalized -state clock models, which include the transverse-field Ising model and ordinar…
