Spontaneous symmetry breaking occurs when a system that is symmetric under certain transformations ends up in a state that is not symmetric. This phenomenon is crucial in various areas of physics, including the BCS theory, where it explains how a system can favor a particular ground state despite being symmetric in its governing equations. In the context of superconductivity, it provides insight into how pairs of electrons can form a condensate state, leading to zero electrical resistance.
