A Cosmological Model Based on a Quadratic Equation of State Unifying Vacuum Energy, Radiation, and Dark Energy
Figure 8
Effect of quantum mechanics (finite value of the Planck constant) on the regularization of the singular Big Bang solution (, dashed line) in our simple semi-classical model. The singularity at is replaced by an inflationary expansion from the vacuum energy era to the radiation era. We can draw an analogy with second order phase transitions where the Planck constant plays the role of finite size effects (see the text for details).
