A translation operator acting in a space with a diagonal metric is introduced to describe the
motion of a particle in a quantum system. We show that the momentum operator and, as a …

The Einstein Equivalence Principle (EEP), stating that all laws of physics take their special-
relativistic form in any local inertial (classical) reference frame, lies at the core of general …

In this work, we describe the process of teleportation between Alice in an inertial frame, and
Rob who is in uniform acceleration with respect to Alice. The fidelity of the teleportation is …

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 …

A detector undergoing uniform acceleration a in a vacuum field responds as though it were
immersed in thermal radiation of temperature T= ℏa/2πkc. An intuitive derivation of this …

In flat spacetime, the Dirac equation is the “square root” of the Klein–Gordon equation in the
sense that, by applying the square of the Dirac operator to the Dirac spinor, one recovers the …

It is concluded in the literature that the Ellis wormhole is unstable under small perturbations
and would either decay to the Schwarzschild black hole or expand away to infinity. While …

We study the effect of gravity on neutrino flavor oscillations when each mass eigenstate is
described by a wave packet instead of a plane wave. Two different approaches for …

One of the major scientific thrusts in recent years has been to try to harness quantum
phenomena to increase dramatically the performance of a wide variety of classical …

By means of Clifford Algebra, a unified language and tool to describe the rules of nature, this
paper systematically discusses the dynamics and properties of spinor fields in curved space …
