Spontaneous symmetry breaking is a term that refers to a phenomenon where the symmetry of a system is broken without any external influence. This concept is commonly used in physics, particularly in the field of particle physics and cosmology. Synonyms for this term include symmetry breaking, symmetry breaking mechanism, and symmetry breaking phase transition. These terms all refer to the same concept of a system losing its symmetry without external influence. This phenomenon is often observed in the behavior of subatomic particles and can lead to the creation of new particles and phenomena. Spontaneous symmetry breaking is a fascinating concept that has important implications for our understanding of the universe.
