Quantum Field Theories on Manifolds with Curved Boundaries: Scalar Fields
A framework allowing for perturbative calculations to be carried out for quantum field theories with arbitrary smoothly curved boundaries is described. It is based on an expansion of the Green function for second order differential operators valid in the neighbourhood of the boundary and which is obtained from a corresponding expansion of of the associated heat kernel derived earlier for arbitr...
متن کاملBose-Einstein condensation for interacting scalar fields in curved spacetime.
We consider the model of self-interacting complex scalar fields with a rigid gauge invariance under an arbitrary gauge group G. In order to analyze the phenomenon of Bose-Einstein condensation finite temperature and the possibility of a finite background charge is included. Different approaches to derive the relevant hightemperature behaviour of the theory are presented.
متن کاملConformal anomalies on Einstein spaces with Boundary
The anomalous rescaling for antisymmetric tensor fields, including gauge bosons, and Dirac fermions on Einstein spaces with boundary has been prone to errors and these are corrected here. The explicit calculations lead to some interesting identities that indicate a deeper underlying structure. Pacs numbers: 03.70.+k, 98.80.Cq Typeset using REVTEX
متن کاملConformal Deformation on Manifolds with Boundary
We consider natural conformal invariants arising from the Gauss-Bonnet formulas on manifolds with boundary, and study conformal deformation problems associated to them. The purpose of this paper is to study conformal deformation problems associated to conformal invariants on manifolds with boundary. From analysis point of view, the problem becomes a non-Dirichlet boundary value problems for ful...
متن کاملInteracting Quantum Fields on a Curved Background
A renormalized perturbative expansion of interacting quantum fields on a globally hyperbolic spacetime is performed by adapting the Bogoliubov Epstein Glaser method to a curved background. The results heavily rely on techniques from microlocal analysis, in particular on Radzikowski’s characterization of Hadamard states by wave front sets of Wightman functions. Quantum field theory on a curved b...
