Review of strongly coupled regimes in gravity with Dyson-Schwinger approach
Marco Frasca, Anish Ghoshal
We analyze various gravity theories involving de-Sitter, quadratic and non-minimally coupled scalar in the light of application of the Dyson-Schwinger technique inv…
Scale-invariant inflation
Massimiliano Rinaldi, Chiara Cecchini, Anish Ghoshal +1
We examine a scalar-tensor model of gravity that is globally scale-invariant. When adapted to a spatially flat Robertson-Walker metric, the equations of motion describe a dynamical…
Inflation and primordial gravitational waves in scale-invariant quadratic gravity with Higgs
Anish Ghoshal, Debangshu Mukherjee, Massimiliano Rinaldi
In scale-invariant models of fundamental physics all mass scales are generated via spontaneous symmetry breaking. In this work, we study inflation in scale-invariant quadratic grav…
Primordial Gravitational Wave Signals in Modified Cosmologies
Nicolás Bernal, Anish Ghoshal, Fazlollah Hajkarim +1
Modified expansion rates in the early Universe prior to big bang nucleosynthesis are common in modified gravity theories, and can have a significant impact on the generation of dar…
