Statistical physics of random systems and nonequilibrium thermodynamics
Theory of random systems, in particular spin glasses, is pursued.
Microscopic approaches bases on the real-replica method combined with TAP equations
are used to understand the mean-field theory of spin glasses.
In nonequilibrium systems dynamical fluctuations in irreversible processes, variational formulation
of nonequilibrium steady states and nonequilibrium thermodynamics beyond
linear response are investigated.
