||Disordered systems and spin glasses: from heuristic to rigorous results
and open problems
||11:00 - 12:00
Vanaf kwart voor 11 is er koffie en thee voor de zaal.
Spin glasses are prototype of complex systems, meaning models with
many equilibrium states. The mean-field theory, proposed 30 years ago
in the context of the 'replica trick', obtained in recent years rigorous
validations. In the talk we will first recall the original heuristic findings
and then discuss both the results for which a rigorous proof is available
and those properties, such as the hierarchical organization of pure
states, that are still only conjectured.
