Light clocks in strong gravitational fields
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
We argue that the time measured by a light clock operating with photons rather than classical light requires a refinement of the standard clock postulate in general relativity. In…
Massive motion in Brans-Dicke geometry and beyond
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
Gravity theories that can be viewed as dynamics for area metric manifolds, for which Brans-Dicke theory presents a recently studied example, require for their physical interpretati…
Geometry and stability of dynamical systems
Raffaele Punzi, Mattias N. R. Wohlfarth
We reconsider both the global and local stability of solutions of continuously evolving dynamical systems from a geometric perspective. We clarify that an unambiguous definition of…
Quantum manifolds with classical limit
Manuel Hohmann, Raffaele Punzi, Mattias N. R. Wohlfarth
We propose a mathematical model of quantum spacetime as an infinite-dimensional manifold locally homeomorphic to an appropriate Schwartz space. This extends and unifies both the st…
Brans-Dicke geometry
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
We reveal the non-metric geometry underlying omega-->0 Brans-Dicke theory by unifying the metric and scalar field into a single geometric structure. Taking this structure seriously…
Propagation of light in area metric backgrounds
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
The propagation of light in area metric spacetimes, which naturally emerge as refined backgrounds in quantum electrodynamics and quantum gravity, is studied from first principles.…
