THEORIES VERSUS EXPERIMENTS IN THE SPIN GLASS SYSTEMS
Résumé
After a rapid description of the main experimental properties of spin glasses (specific heat, critical temperature, hysterisis and metastability), we show how the actual theories (phenomenology, mean field theory) are being developed. The concept of frustration, and its link to gauge theories seems promising, but a lot of work has to be done in order to understand this new phase transition.
