Goldstone

Goldstone refers to a concept in physics where, when a continuous symmetry in a system is spontaneously broken, it results in the emergence of massless, low-energy particles called Goldstone bosons. Imagine a perfectly symmetrical object choosing a specific position or orientation, breaking that symmetry. Similarly, in physical systems, when the underlying rules are symmetric but the system settles into a particular state, Goldstone bosons appear as a consequence. They are fundamental in understanding phenomena in particle physics and condensed matter systems, revealing how symmetrical laws lead to the emergence of new particles and behaviors.
