Modular structure of chiral Fermi fields in conformal quantum field theory
Beschreibung:
The following thesis deals with the modular theory of Fermi fields in low dimensions; in particular, making use of the algebraic approach to quantum field theory, we have investigated the behaviour of two- dimensional theories which split into two separate copies of chiral fields, each one of them depending on one lightray variable at a time only. The remarkable result we have found is the existence of a vacuum preserving isomorphism β connecting the vacuum states between the algebra of N Fermi fields localised in one single interval and the algebra of one Fermi field localised in N disjoin...
