Perturbative algebraic quantum field theory and the quantization of submanifold embeddings
Speaker:Dr. Jochen Zahn (Univ. Vienna)
Abstract:Im Rahmen des Vienna Theory Lunch Seminars. Abstract: We review the framework of perturbative algebraic quantum field theory, which provides a mathematically rigorous formulation of perturbative quantum field theories and allows for a generalization to curved spacetimes. We present a recent application of the framework, namely the perturbative quantization of embeddings of d-dimensional submanifolds into n-dimensional Minkowski space, based on the Nambu-Goto action. The model has the status of an effective field theory. We show the absence of anomalies for any dimensions d and n, so in particular, there is no critical dimension n for the case of string theory (d=2).
