They represent tunneling transitions from one vacuum state to another.

Once this is accepted, the energy of the vacuum state cannot be talked out of existence.

According to the string theorists, there are some 10 to the power 500 possible equations for the vacuum state of the universe.

These processes are important in the vacuum state and renormalization of a quantum field theory.

In quantum field theory, the vacuum state may be degenerate.

In this case, the different materials are different vacuum states.

In modern particle physics, the vacuum state is considered as the ground state of matter.

The effects will spread at light speed, transforming everything to the true vacuum state.

The vacuum state is the set of all negative levels.

The lowest energy state is called the vacuum state and may be very complicated.
