Second-order phase transitions display this phenomenon according to Landau, while if this process occurs while the ground state is invariant under the given charge, it results in the creation of Goldstone bosons.
In trinification theory, this process results in the transition from SU 3 sub L cross SU 3 sub R to SU 2 cross U 1 over Z 2. The absence of this process in systems with equal to or fewer than two dimensions allows the creation of long-range fluctuations with little energy cost according to the Mermin-Wagner theorem, while in the electroweak interaction this process results in the reduction of the SU 2  cross U 1 group to a U 1 group via the Higgs mechanism, resulting in the creation of W and Z boson mass. Second-order phase transitions display this phenomenon according to Landau, while if this process occurs while the ground state is invariant under the given charge, it results in the creation of Goldstone bosons. For 10 points, name this process in which a system with a particular continuous symmetry enters a state in which said symmetry is no longer present.
In trinification theory, this process results in the transition from SU 3 sub L cross SU 3 sub R to SU 2 cross U 1 over Z 2.
