abstract

We give a characterization of Drinfeld centers of fusion categories as non-degenerate braided fusion categories containing a Lagrangian algebra. Further we study the quotient of the monoid of non-degenerate braided fusion categories modulo the submonoid of the Drinfeld centers and show that its formal properties are similar to those of the classical Witt group.

Many-body chirality of topological stabilizer states

quant-ph · 2026-06-18 · unverdicted · novelty 7.0

Many-body chirality for Z_d^(k) stabilizer states equals mirror non-invariance of anyon data, is intrinsically four-partite, and states with d>2 also show intrinsic imaginarity not removable by local unitaries.

$K$-Theoretic Obstructions to Linearizing QCA Representations

math.AT · 2026-06-17 · unverdicted · novelty 7.0

Develops K-theoretic obstruction theory for linearizing QCA representations over arbitrary fields, extracting universal classes and computing homotopy types over point/line/plane in the complex unitary case.

Hypergroup Symmetry in Relative Quantum Field Theories and Chiral Algebras

hep-th · 2026-06-03 · unverdicted · novelty 7.0

Framework for hypergroup symmetries in relative QFTs establishes one-to-one correspondence between finite symmetries and finite-index conformal embeddings in rational chiral algebras, with implications for gluing left-right symmetries and boundary conditions in 2D CFTs.

Higher Gauging and Non-invertible Condensation Defects

hep-th · 2022-04-05 · unverdicted · novelty 7.0

Higher gauging of 1-form symmetries on surfaces in 2+1d QFT yields condensation defects whose fusion rules involve 1+1d TQFTs and realizes every 0-form symmetry in TQFTs.

Notes on (-2)-form symmetries

hep-th · 2026-06-04 · conditional · novelty 6.0

(-2)-form symmetries are realized as non-genuine defects in the Symmetry TFT and relate theories with different anomaly or associator data.
