Cosmological Implications of Unimodular Gravity
Pankaj Jain, Atul Jaiswal, Purnendu Karmakar +2
We consider a model of gravity and matter fields which is invariant only under unimodular general coordinate transformations (GCT). The determinant of the metric is treated as a se…
Testing Unimodular Gravity
Pankaj Jain, Purnendu Karmakar, Subhadip Mitra +2
We consider models of gravitation that are based on unimodular general coordinate transformations (GCT). These transformations include only those which do not change the determinan…
Cosmological Perturbation Analysis in a Scale Invariant Model of Gravity
Pankaj Jain, Purnendu Karmakar, Subhadip Mitra +2
We consider a model for gravity that is invariant under global scale transformations. It includes one extra real scalar field coupled non-minimally to the gravity fields. In this m…
