Fermion vacuum energies in brane world models

The fermion representations and boundary conditions in five dimensional anti de Sitter space are described in detail. In each case the one loop effective action is calculated for massless fermions. The possibility of topological or Wilson loop symmetry breaking is discussed. Pacs numbers: 04.62+v, 11.10.Kk, 11.15.Ex Typeset using REVTEX

Calculating Vacuum Energies in Quantum Field Theory

A new approach to generalised Casimir type of problems is derived within the context of renormalisable quantum field theory (QFT). We study the simplest case of a massive fluctuating boson field coupled to a time-independent background potential. We use analytic properties of scattering data to compute the relevant Green’s functions at imaginary momenta, which in turn yields a simple and effici...

Vacuum Energies and Effective Potential in Light-Cone Field Theories

Vacuum energies are computed in light-cone field theories to obtain effective potentials which determine vacuum condensate. Quantization surfaces interpolating between the light-like surface and the usual spatial one are useful to define the vacuum energies unambiguously. The GrossNeveu, SU(N) Thirring, and O(N) vector models are worked out in the large N limit. The vacuum energies are found to...

On vacuum energies and renormalizability in integrable quantum field theories

We compute for various perturbed conformal field theories the vacuum energies by means of the thermodynamic Bethe ansatz. Depending on the infrared and ultraviolet divergencies of the models, governed by the scaling dimensions of the underlying perturbed conformal field theory in the ultraviolet, the vacuum energies exhibit different types of characteristics. In particular, for the homogeneous ...

Strong Interactions at Low Energies

The lectures review some of the basic concepts relevant for an understanding of the low energy properties of the strong interactions: chiral symmetry, spontaneous symmetry breakdown, Goldstone bosons, quark condensate. The effective field theory used to analyze the low energy structure is briefly sketched. As an illustration, I discuss the implications of the recent data on the decay K → ππeν f...
