 Through interactions with others of its kind, this state collectively orders to form a macroscopically ordered metastable state H, further lowering its energy as a result.The new state has a broken symmetry with respect to the G or E state, and may also involve further relaxation compared to the I state.The barrier EB prevents state H from reverting to the ground state G. If the barrier is sufficiently large compared to thermal energy kBT, where kB is the Boltzmann constant, the H state can be stable indefinitely.
