A Torsion-Driven Generalisation of Unimodular Gravity

Abstract

We present an Einstein Cartan Kalb Ramond model that yields a generalisation of unimodular gravity in which the dynamics are driven by torsion rather than curvature. Using a simple ansatz, we discuss how different possible cosmological scenarios can arise on considering geometries that include torsion tensors and provide a framework for modifying GR using Emergent Reimann Geometry.
