The minimum elements of matter which can be observed are hadrons and leptons. Hadrons are particles interacting with strong forces, such as proton and pion, and are composed of quarks and gluons. Owing to the color confinement phenomenon, quarks and gluons are confined in the hadrons and are never observed …

These particles are called the Goldstone- or sometimes Nambu-Goldstone bosons and the proof of their existance was then given by Goldstone, Salam and Weinberg [7].

WitrynaDespite their ubiquity, a fundamental understanding of amorphous solids and the glass transition has yet to be obtained. This is in stark contrast to our knowledge of crystalline solids, which result by first-order phase transitions and in which phonons (collective Nambu-Goldstone modes) develop to transport thermal energy. WitrynaWe demonstrate that when there is spontaneous symmetry breaking in any system, relativistic or non-relativistic, the dynamic of the Nambu-Goldstone bosons is governed by the Quantum Yang-Baxter equations. These equations describe the triangular
