Goal: Understand some physical properties of mean-field spin glasses in the low-T phase: the structure of the free-energy landscape, the response of the system to applied magnetic fields.
Key concepts: full-RSB, magnetic susceptibility, linear response, ultrametricity.
Notes
- [1] - This is reflected in the formula above: one is averaging over all possible pure states, meaning that the system has enough time to sample them according to their thermal weight .
