At low temperatures the true vacuum state may have lower energy than the false vacuum state, in an analogous fashion to how solid ice has lower energy than liquid water.
The supercooling of the universe may therefore have induced a rapid phase transition from the false vacuum state to the true vacuum state, in which the cosmological constant is essentially zero.
What has is a vacuum state run by warlords that is now the centre of Mediterranean people-smuggling.
The contribution of a field to the energy density (and therefore the mass density) and the pressure of the vacuum state need not have been zero in the past, even if it is today.
Conceivably, if the universe is in a false vacuum state, a collider such as Cern's could punch a hole in the fabric of space, like a hole in the dam, allowing the entire universe to fall out of the false vacuum and settle at a lower level.
where ∣0> is the photonic vacuum state.
where denotes the vacuum state of the optical field.
Squeezing at the quantum limit produces a squeezed vacuum state, as recently demonstrated [8].
In this paper, we report the successful detection of the ionization of gases in vacuum state.
Under this assumption, the final state is the exciton vacuum state |0>.
Therefore, the red-shifted in absorption spectra is occurred with respect to the vacuum state.
