Cosmological implications of the transition from the false vacuum to the true vacuum state

Understand

We study the cosmology with the running dark energy.

• The parametrization of dark energy with the respect to the redshift is derived from the first principles of quantum mechanics.
• Energy density of dark energy is obtained from the quantum process of transition from the false vacuum state to the true vacuum state.
• This is the class of the extended interacting $\Lambda$CDM models.
