Gravitational wave propagation in a geometric condensate in Starobinsky cosmology
Abstract In this paper we propose a new paradigm for cosmology: a time dependent scalar condensate background originated from the quadratic $$(R + \alpha R^2)$$ ( R + α R 2 ) Starobinsky model, where R is the Ricci scalar and $$\alpha $$ α the coupling constant. In weak gravity limit the system deco...
