On Bosonic Wightman Quantum Field Theories
Andreas Raab
We prove that field operators in a Wightman quantum field theory generally have self-adjoint extensions. If the theory is bosonic and the field operators also obey canonical commut…
Quantum-field theories as representations of a single -algebra
Andreas Raab
We show that many well-known quantum field theories emerge as representations of a single -algebra. These include free quantum field theories in flat and curved space-times,…
Effective quantum field theories in general spacetimes
Andreas Raab
We introduce regular charts as physical reference frames in spacetime, and we show that general spacetimes can always be fully captured by regular charts. Effective quantum field t…
On the representation of effective quantum field theories
Andreas Raab
We discuss a general model for effective quantum field theories (QFTs), which for example comprises quantum chromodynamics and quantum electrodynamics. We assume in the model a per…
An approach to nonstandard quantum mechanics
Andreas Raab
We use nonstandard analysis to formulate quantum mechanics in hyperfinite-dimensional spaces. Self-adjoint operators on hyperfinite-dimensional spaces have complete eigensets, and…
