Dirac spinor in a nonstationary Godel-type cosmological Universe

Abstract

In the present article we solve, via separation of variables, the massless Dirac equation in a nonstationary rotating, causal G\"odel-type cosmological universe, having a constant rotational speed in all the points of the space. We compute the frequency spectrum. We show that the spectrum of massless Dirac particles is discrete and unbounded.Comment: 6pp, IVIC-CFLE 93/0
