Collective modes and Broken Symmetry
1,What is symmetry in physics? A symmetry transformation is a change in our point of view that does not change the result of possible experiments.In particular, a symmetry transformation that is infinitesimally close to being trivial can be represented by a linear unitary operator that is
2,Symmetry breaking: Explicit symmetry breaking Spontanous symmetry breaking
3,Why broken symmetry in low tempreture?
