GraviGUT unification with revisited Pati-Salam model
Stephon Alexander, Bruno Alexandre, Michael Fine +2
We propose a graviGUT unification scheme based on the simple orthogonal group that resolves the chiral duplication of weak isospin in Pati--Salam mod…
Spontaneous Symmetry Breaking in Graviweak Theory
Stephon Alexander, Bruno Alexandre, Michael Fine +2
Graviweak theory seeks to unify gravity (specifically in its self-dual formulation) with the weak interaction, preying on their parallel chiral structures. In this paper we…
Overall signature of the metric and the cosmological constant
Bruno Alexandre, Steffen Gielen, João Magueijo
We consider a little known aspect of signature change, where the overall sign of the metric is allowed to change, with physical implications. We show how, in different formulations…
Unitary and Vilenkin's wave functions
Bruno Alexandre, Raymond Isichei, João Magueijo
It is remarkably difficult to reconcile unitary and Vilenkin's wave function. For example, the natural conserved inner product found in quantum unimodular gravity applies to the Ha…
