Leticia Cugliandolo studies the slow nonequilibrium dynamics of spin glass systems and other complex systems. Her theoretical treatment distinguishes equilibrium relaxation from aging in nonequilibrium systems, where a response depends on how long the system has already been evolving. Two-time correlation functions and responses can violate an equilibrium fluctuation-dissipation theorem, leading to carefully defined effective-temperature descriptions in suitable regimes. Solvable mean-field models connect this dynamics with a complicated free-energy landscape, supplying tests of which features extend beyond a particular material.[ref]
