Superselection Sectors and General Covariance. I
This paper is devoted to the analysis of charged superselection sectors in the framework of the locally covariant quantum field theories. We shall analize sharply localizable charges, and use net-cohomology of J.E. Roberts as a main tool. We show that to any 4-dimensional globally hyperbolic spacetime it is attached a unique, up to equivalence, symmetric tensor C∗−category with conjugates (in c...
متن کاملBrane Baldness vs. Superselection Sectors
The search for intersecting brane solutions in supergravity is a large and profitable industry. Recently, attention has focused on finding localized forms of known ‘delocalized’ solutions. However, in some cases, a localized version of the delocalized solution simply does not exist. Instead, localized separated branes necessarily delocalize as the separation is removed. This phenomenon is relat...
متن کاملGroup Averaging, Positive Definiteness and Superselection Sectors
I discuss group averaging as a method for quantising constrained systems whose gauge group is a noncompact Lie group. Focussing on three case studies, I address the convergence of the averaging, possible indefiniteness of the prospective physical inner product and the emergence of superselection sectors.
متن کاملHomotopy, net-cohomology and superselection sectors in globally hyperbolic spacetimes
In this paper we show that the superselection sectors of a net of local observables, in arbitrary 4-dimensional globally hyperbolic spacetimes, define, as it happens in the Minkowski space, a C∗−category in which the charge structure manifests itself by the existence of a tensor product, a symmetry and a conjugation. The mathematical framework is that of the net-cohomology of posets according t...
