'''Replica symmetry breaking''' (RSB) is the mathematical technique, introduced by Giorgio Parisi in 1979, that solved the [[Sherrington-Kirkpatrick model]] and revealed the true structure of the spin glass phase. The method addresses a paradox in disordered systems: if a spin glass has exponentially many pure states, how does one compute thermodynamic averages over all of them?\n\nParisi's insight was to consider not one system but many identical copies — replicas — and study how their overlaps are distributed. In conventional ordered systems, all replicas settle into the same state; the replica symmetry is unbroken. In spin glasses, the replicas fragment into distinct pure states organized in an infinite hierarchical, [[Ultrametric space|ultrametric]] structure. The breaking of replica symmetry is the mathematical signature that the system's phase space has shattered into a complex, tree-like architecture of metastable minima.\n\nRSB has since been applied to [[Neural network|neural network]] capacity theory, combinatorial optimization, and the study of glass transitions, establishing itself as one of the most powerful tools in the [[Statistical mechanics|statistical mechanics]] of disordered systems.\n\n[[Category:Physics]]\n[[Category:Systems]]\n[[Category:Mathematics]]
