Abstract

Modular invariants satisfy remarkable fusion rules. Let Z be a modular invariant associated to a braided subfactor N ⊂ M. The decomposition of the non-normalized modular invariants ZZ* and Z*Z into sums of normalized modular invariants is related to the decomposition of the full induced M-M system of sectors.

Modular invariants from subfactors: Type I coupling matrices and intermediate subfactors

Jens Böckenhauer, David Evans

A braided subfactor determines a coupling matrix Z which commutes with the S- and T-matrices arising from the braiding. Such a coupling matrix is not necessarily of “type I”, i.e. in general it does not have a block-diagonal structure which can be reinterpreted as the diagonal coupling matrix with respect to a suitable extension. We show that there are always two intermediate subfactors which correspond to left and right maximal extensions and which determine “parent ” coupling matrices Z ± of type I. Moreover it is shown that if the intermediate subfactors coincide, so that Z + = Z − , then Z is related to Z + by an automorphism of the extended fusion rules. The intertwining relations of chiral branching coefficients between original and extended S- and T-matrices are also clarified. None of our results depends on non-degeneracy of the braiding, i.e. the S- and T-matrices need not be modular. Examples from SO(n) current algebra models illustrate that the parents can be different, Z + ̸ = Z − , and that Z need not be related to a type I invariant by such an automorphism. 1

New subfactors associated with closed systems of sectors

Karl-Henning Rehren

A theorem is derived which (i) provides a new class of subfactors which may be interpreted as generalized asymptotic subfactors, and which (ii) ensures the existence of two-dimensional local quantum field theories associated with certain modular invariant matrices.

Modular S and T Matrices: Linking CFT, Quantum Groups, and Topological Phases — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: Modular S and T matrices from CFT encode braiding and fusion in quantum group representations at roots of unity, linking topological phases to geometric invariants. | MATH: Modular group SL(2,Z) generators: S (modular transformation τ → -1/τ), T (τ → τ+1). S and T satisfy S² = (ST)³ = C (charge conjugation), S⁴ = I. Quantum group U_q(g) at q = e^{π i / k} yields finite-dimensional representations with fusion rules N_{ij}^k. S-matrix elements: S_{ab} = (1/√N) Σ_c d_c e^{2π i (h_a + h_b - h_c)}. T-matrix: T_{ab} = δ_{ab} e^{2π i h_a - c/24}. | CONNECTION: S-matrix eigenvalues relate to golden ratio φ = 1.618 in SU(2)_k at k=1: S = (1/√2)[1 1; 1 -1]. For k=3, S entries involve φ: S_{11} = (1/√5) sin(π/5) = φ/√5 ≈ 0.7236. Fusion rules for Fibonacci anyons: τ × τ = 1 + τ, with quantum dimension d_τ = φ = 1.618. Braiding eigenvalues: R^{ττ}_1 = e^{-4π i/5}, R^{ττ}_τ = e^{3π i/5}, giving phases related to 0.618 (1/φ). | DEPTH: 8 — Directly connects modular tensor categories to topolo Author: Andrew Stewart Caldin, Independent Researcher, UK.

MODULAR INVARIANCE AND FUSION RULE ALGEBRAS: CLASSIFICATION OF THE THREE-OPERATOR CASE

Michele Caselle, G. Ponzano

We show how to handle together constraints coming from associativity, modular invariance and analyticity in RCFT's. In particular, looking at the theories with three operators we classify fusion rule algebras, central charges and conformal weights fulfilling such constraints. We also show that all allowed theories with three operators are algebraic.

Critical Phenomena, modular invariants and operator algebras

David Evans

We review the framework subfactors provide for understanding modular invariants. We discuss the structure of a generalized Longo-Rehren subfactor and the relationship between the coupling matrices of such subfactors, modular invariance and local extensions. We relate results of Kostant, in the context of the McKay correspondence for finite subgroups of SU(2), to subfactors. A direct proof of how alpha-induction produces modular invariants is presented.
