Dark energy from Geometrothermodynamics

Understand

Geometrothermodynamics is a geometric theory which combines thermodynamics with contact and Riemannian geometry.

• In this work we use the formalism of geometrothermodynamics to infer cosmological models which predict the observed speed up.
• As a relevant consequence, our simple model shows dynamical properties which seem to fairly well describe the late time universe dynamics.
• To do so, we use geometric considerations about constant thermodynamic curvature and derive the model of a fluid which is expected to \emph{naturally} reproduce the dark energy effects.
