Idea

A conformal net is a local net of observables that describes (2-dimensional) conformal field theory in the framework of AQFT.

Relation to vertex operator algebras

Subject to some conditions a vertex operator algebra may be turned into a conformal net and vice versa (Capri-Kawahigahshi-Longo-Weiner 15).

Relation to spectral triples

Superconformal nets encoding 2d SCFTs may be related to local nets of spectral triples (#CHKL 09) (an incarnation of “2-spectral triples”, see there for more).

Examples

Free fermion

(DH, section 4)

Fer n(I)Cl(L 2(I, nS)) Fer_n(I) \coloneqq Cl(L^2(I, \mathbb{R}^n \otimes S))

Fundamentals

Standard AQFT references on conformal nets include

and lots of others…

A somewhat novel take on conformal nets is presented and studied in

where conformal nets are arranged into a tricategory with symmetric monoidal structure that is a delooping of the bicategory of von Neumann algebras and bimodules between these. Among other things, this work connects the AQFT notion of conformal nets with the FQFT notion of cobordism representations.

Relation to 2-spectral triples is discussed in terms of vertex operator algebras
