On dilation symmetries arising from scaling limits
Henning Bostelmann, Claudio D'Antoni, Gerardo Morsella
Quantum field theories, at short scales, can be approximated by a scaling limit theory. In this approximation, an additional symmetry is gained, namely dilation covariance. To unde…
Scaling algebras and pointlike fields: A nonperturbative approach to renormalization
Henning Bostelmann, Claudio D'Antoni, Gerardo Morsella
We present a method of short-distance analysis in quantum field theory that does not require choosing a renormalization prescription a priori. We set out from a local net of algebr…
Abelian Strict Approximation in AW*-Algebras and Weyl-von Neumann Type Theorems
Claudio D'Antoni, Laszlo Zsido
In this paper, for a C*-Algebra A with M = M(A) an AW*-algebra, or equivalently, for an essential, norm-closed, two-sided ideal A of an AW*-algebra M, we investigate the strict app…
Nuclearity and Thermal States in Conformal Field Theory
Detlev Buchholz, Claudio D'Antoni, Roberto Longo
We introduce a new type of spectral density condition, that we call L^2-nuclearity. One formulation concerns lowest weight unitary representations of SL(2,R) and turns out to be eq…
Scaling Algebras and Superselection Sectors: Study of a Class of Models
Claudio D'Antoni, Gerardo Morsella
We analyse a class of quantum field theory models illustrating some of the possibilities that have emerged in the general study of the short distance properties of superselection s…
Implementation of conformal covariance by diffeomorphism symmetry
Claudio D'Antoni, Klaus Fredenhagen, Soeren Koester
Every locally normal representation of a local chiral conformal quantum theory is covariant with respect to global conformal transformations, if this theory is diffeomorphism covar…
