Physicists Uncover Why Detecting Strong-to-Weak Symmetry Breaking May Be Impossible Understanding Symmetry and Spontaneous Symmetry Breaking Fundamental Concepts Behind Symmetry in Physics When a system changes but a key physical property remains constant, that property is known as a "symmetry." Spontaneous symmetry breaking (SSB) happens when the system departs from this symmetry at most stable, lowest-energy state. Physicists have recently discovered that a new form of SSB can arise in open quantum systems — those influenced by quantum effects and capable of exchanging energy, particles or information with their surroundings. They found that symmetry in such systems may be classified as either "strong" or "weak." A strong symmetry means both the system and its environment individually uphold the symmetry, whereas a weak symmetry appears only when the two are considered together. When a strong symmetry gives way to weak one, entirely new phases of matter...
