Loop quantization as a continuum limit
Elisa Manrique, Robert Oeckl, Axel Weber +1
We present an implementation of Wilson's renormalization group and a continuum limit tailored for loop quantization. The dynamics of loop quantized theories is constructed as a con…
General boundary quantum field theory: Timelike hypersurfaces in Klein-Gordon theory
Robert Oeckl
We show that the real massive Klein-Gordon theory admits a description in terms of states on various timelike hypersurfaces and amplitudes associated to regions bounded by them. Th…
General boundary quantum field theory: Foundations and probability interpretation
Robert Oeckl
We elaborate on the proposed general boundary formulation as an extension of standard quantum mechanics to arbitrary (or no) backgrounds. Temporal transition amplitudes are general…
States on timelike hypersurfaces in quantum field theory
Robert Oeckl
We investigate the possibility of defining states on timelike hypersurfaces in quantum field theory. To this end we consider hyperplanes in the real massive Klein-Gordon theory usi…
Combinatorics of n-point functions via Hopf algebra in quantum field theory
Angela Mestre, Robert Oeckl
We use a coproduct on the time-ordered algebra of field operators to derive simple relations between complete, connected and 1-particle irreducible n-point functions. Compared to t…
