DeWitt’s theory on superconductors in gravitational fields is re-derived in the low velocity limit and linear gravity from the Klein-Gordon equation for an ensemble of charged spinless bosons. The solution has a phase singularity that gives rise to

It has been shown that, even in linear gravitation, the curvature of space-time can induce ground state degeneracy in quantum systems, break the continuum symmetry of the vacuum and give rise to condensation in a system of identical particles. Conden

Single-vertex Feynman diagrams represent the dominant contribution to physical processes, but are frequently forbidden kinematically. This is changed when the particles involved propagate in a gravitational background and acquire an effective mass. P

We report on the behavior 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 and motions. The calculations are performed in the external field appro

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 momentum is possible only when the acceleration is time-dependent. This r

This chapter deals with general relativistic effects on spin-flavour oscillations above the core of type II supernovae. The evolution equation is derived and the relative magnitudes of the terms in the Hamiltonian are discussed. These terms arise fro
