Dynamical dark energy with AdS-to-dS and dS-to-dS transitions: Implications for the $H_0$ tension

Özgür Akarsu, Leandros Perivolaropoulos, Anna Tsikoundoura +2

We investigate the dynamics and cosmological implications of dark energy (DE), modeled as a scalar field with a hyperbolic tangent potential that induces a smooth shift in the effe…
