| Abstract: | We prove that, just below the critical temperature, the mean field p-spins interaction model, for p suitably large, spontaneously decomposes into different states. The asymptotic overlaps between any two different states
are zero. Under a mild (unproven) hypothesis on the weight distribution of these states, we prove that they are pure states.
This situation is called in physics “one level of symmetry breaking”.
