THE GOLDSTONE THEOREM It doesn't matter for our discussion…
““THE GOLDSTONE THEOREM It doesn't matter for our discussion that the broken symmetry of our world chooses a particular direction not in actual geometrical space but rather in an abstract space. There is one feature we can carry over from the previous consideration: Spontaneous symmetry breaking implies the existence of waves. The spin-waves in the ferromagnetic world of our model are replaced by excitations in the abstract space of particle properties, where the symmetry breaking actually occurs. In this world, there must be equivalent excitations, waves: The so-called Goldstone theorem says that every symmetry of the laws of nature that is not also a symmetry of the ground state implies the existence of an elementary particle; it even fixes the properties of that particle.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Spontaneous symmetry breaking in abstract spaces predicts new particle-like excitations called Goldstone bosons.
In simple terms: Broken symmetry creates waves that become particles.
