Matter is in its ground state, and contains no thermal energy.

I call it the ground state of the resting mind.

In all, half a century passed before the continuum returned to the ground state.

In general, the atoms are excited to a level that is two or three levels above the ground state.

Its energy is above the ground state but below that of the other isomers.

In this case, we can think of the atom as having two ground states.

Let be concentration of active centers in the ground state.

There's little doubt that these atoms spent most of their time in the ground state.

The kinetic energy of the ground state cannot be removed.

From this point on, any extra particle added will go into the ground state.
