Talk on categorical Ising models and SymTFT at IHES

Kramers-Wannier Duality in Non-Abelian Ising Models from SymTFT

IHES Seed Seminar of Mathematics and Physics — Bures-sur-Yvette, France

Generalized Ising models with non-abelian and non-invertible symmetries can be constructed from symmetry topological field theory. Gauging changes the topological boundary condition, while bulk mirror symmetry produces Kramers-Wannier duality.

GGI, BPS Dynamics and Quantum Mathematics — Florence, Italy

Bethe/Gauge correspondence for superspin chains and the associated R-matrices obtained from supersymmetric localization, based on arXiv:2110.15112 and arXiv:2308.12333.

Dynamical R-Matrix for Superspin Chains from the Bethe/Gauge Correspondence

CERN TH String Theory Seminar — Geneva, Switzerland

A computation of dynamical R-matrices for \(\mathfrak{gl}(m|n)\) spin chains from Janus interfaces in three-dimensional \(\mathcal N=2\) theories, based on arXiv:2308.12333.

Line Operators and Cherkis Bows

Simons Center for Geometry and Physics — Stony Brook, USA

Phase spaces of line operators in four-dimensional Chern-Simons theory are identified with Cherkis bow varieties, suggesting their quantizations furnish representations of Yangians. Based on arXiv:2211.00049.

Relating Integrable Spin Chains to Gauge Theories via String Theory

Institute for Advanced Study High Energy Theory Seminar — Princeton, USA

A string-theoretic explanation of the Bethe/Gauge correspondence for superspin chains and gauge-theory duals of non-compact chains in terms of handsaw-type quivers. Based on arXiv:2110.15112.
