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…

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…

Unimodular JT gravity and de Sitter quantum cosmology
Bruno Alexandre, Altay Etkin, Farbod-Sayyed Rassouli
In this work, we show that a gauge-theoretic description of Jackiw-Teitelboim (JT) gravity naturally yields a Henneaux-Teitelboim (HT) unimodular gravity via a central extension of…
