Abstract

Spontaneous symmetry breaking is an important concept that applies to particle physics to nuclear, condensed matter, cold atomic, astrophysics, to even early universe cosmology, chemistry, and biology. In particular, continuous symmetries produce Nambu-Goldstone bosons that govern the phenomena at long wavelengths and small energies. However, answers to truly basic questions, such as the number of Nambu-Goldstone bosons or their dispersion relations, had been answered on case-by-case basis without a general framework. The authors recently proposed a framework to understand Nambu-Goldstone bosons in a unified fashion. This work extends the celebrated Nambu-Gold-stone theorem in Lorentz-invariant systems. We demonstrate what had not been clear and what is now using explicit examples of magnets and crystals.
