Evanescent Particles
Daniele Colosi, Robert Oeckl
Massive Klein-Gordon theory is quantized on a timelike hyperplane in Minkowski space using the framework of general boundary quantum field theory. In contrast to previous work, not…
Locality and General Vacua in Quantum Field Theory
Daniele Colosi, Robert Oeckl
We extend the framework of general boundary quantum field theory (GBQFT) to achieve a fully local description of realistic quantum field theories. This requires the quantization of…
The vacuum as a Lagrangian subspace
Daniele Colosi, Robert Oeckl
We unify and generalize the notions of vacuum and amplitude in linear quantum field theory in curved spacetime. Crucially, the generalized notion admits a localization in spacetime…
Complex structures and quantum representations for scalar QFT in curved spacetimes
Daniele Colosi, Max Dohse
We confirm the equivalence of the Schrödinger representation and the holomorphic one, based on previous results of the General Boundary Formulation (GBF) of quantum field theory. O…
Quantum field theory on timelike hypersurfaces in Rindler space
Daniele Colosi, Dennis Rätzel
The general boundary formulation of quantum field theory is applied to a massive scalar field in two dimensional Rindler space. The field is quantized according to both the Schrödi…
S-Matrix for AdS from General Boundary QFT
Daniele Colosi, Max Dohse, Robert Oeckl
The General Boundary Formulation (GBF) is a new framework for studying quantum theories. After concise overviews of the GBF and Schrödinger-Feynman quantization we apply the GBF to…
