Ground state physics

WebThe simplest definition of the ground state of an atom refers to: Ground State (of an atom): the lowest possible energy level of the atom in question. To define this more broadly, we can say that the ground state is the state in which atoms are found if they are not charged or excited by external sources. WebThe ground state of a quantum-mechanical system is its stationary state of lowest energy; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater …
