Spontaneous symmetry breaking is a spontaneous process of symmetry breaking, by which a physical system in a symmetric state spontaneously ends up in an asymmetric state. In particular, it can describe systems where the equations of motion or the Lagrangian obey symmetries, but the lowest-energy vacuum solutions do not exhibit that ...
3 set 2019 · Aron J. Beekman, Louk Rademaker, Jasper van Wezel. Perhaps the most important aspect of symmetry in physics is the idea that a state does not need to have the same symmetries as the theory that describes it. This phenomenon is known as spontaneous symmetry breaking.

24 lug 2003 · 4.2 Spontaneous symmetry breaking. Spontaneous symmetry breaking (SSB) occurs in a situation where, given a symmetry of the equations of motion, solutions exist which are not invariant under the action of this symmetry without any explicit asymmetric input (whence the attribute “spontaneous”).

17 nov 2013 · phase symmetry associated with conservation of He4 atom number. In superconductors {the classic case being bad metals at low temperatures { the symmetry that is broken is a local (gauged) symmetry, associated to electron number, to which photons respond. Several cases of spontaneous symmetry breaking are important within the standard model.
