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…
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…
Geometric obstruction of black holes
Raffaele Punzi, Frederic P. Schuller, Mattias N. R. Wohlfarth
We study the global structure of Lorentzian manifolds with partial sectional curvature bounds. In particular, we prove completeness theorems for homogeneous and isotropic cosmologi…
Lower Neutrino Mass Bound from SN1987A Data and Quantum Geometry
G. Lambiase, G. Papini, R. Punzi +1
A lower bound on the light neutrino mass is derived in the framework of a geometrical interpretation of quantum mechanics. Using this model and the time of flight delay data…
Neutrino optics and oscillations in gravitational fields
G. Lambiase, G. Papini, R. Punzi +1
We study the propagation of neutrinos in gravitational fields using wave functions that are exact to first order in the metric deviation. For illustrative purposes, the geometrical…
