Equivalent forms of Dirac equations in curved spacetimes and generalized de Broglie relations

Mayeul Arminjon, Frank Reifler

One may ask whether the relations between energy and frequency and between momentum and wave vector, introduced for matter waves by de Broglie, are rigorously valid in the presence…

General reference frames and their associated space manifolds

Mayeul Arminjon, Frank Reifler

We propose a formal definition of a general reference frame in a general spacetime, as an equivalence class of charts. This formal definition corresponds with the notion of a refer…

Measuring a Kaluza-Klein radius smaller than the Planck length

Frank Reifler, Randall Morris

Hestenes has shown that a bispinor field on a Minkowski space-time is equivalent to an orthonormal tetrad of one-forms together with a complex scalar field. More recently, the Dira…

Geometric Origin of Physical Constants in a Kaluza-Klein Tetrad Model

Frank Reifler, Randall Morris

An important feature of Kaluza-Klein theories is their ability to relate fundamental physical constants to the radii of higher dimensions. In previous Kaluza-Klein theory, which un…

Hestenes' Tetrad and Spin Connections

Frank Reifler, Randall Morris

Defining a spin connection is necessary for formulating Dirac's bispinor equation in a curved space-time. Hestenes has shown that a bispinor field is equivalent to an orthonormal t…

Inertial mass and the quantum vacuum fields

Bernard Haisch, Alfonso Rueda, York Dobyns

Even when the Higgs particle is finally detected, it will continue to be a legitimate question to ask whether the inertia of matter as a reaction force opposing acceleration is an…
