Condensation phenomena in gravity

Giorgio Papini

Gravity can play a role in critical phenomena. Topological singularities induce ground state degeneracy and break the continuum symmetry of the vacuum. They also generate momenta o…

Gravitational qubits

Giorgio Papini

We report on the behaviour of two-level quantum systems, or qubits, in the background of rotating and non-rotating metrics and provide a method to derive the related spin currents…

Long range order in gravity

Giorgio Papini

Gravity induced condensation takes the form of momentum alignment in an ensemble of identical particles. Use is made of a one-dimensional Ising model to calculate the alignment per…

Structured objects in quantum gravity. The external field approximation

Giorgio Papini

In the external field approximation (EFA) gravity and inertia are represented by a two-point vector that is the byproduct of symmetry breaking. The vector is accompanied by the app…

Spin and maximal acceleration

Giorgio Papini

We study the spin current tensor of a Dirac particle at accelerations close to the upper limit introduced by Caianiello. Continual interchange between particle spin and angular mom…

Classical and Quantum Aspects of Particle Propagation in External Gravitational Fields

Giorgio Papini

In the study of covariant wave equations, linear gravity manifests itself through the metric deviation and a two-point vector potential itself constructed from $γ_{μ…
