Leticia Fernanda Cugliandolo (born 1965)[1] is an Argentine condensed matter physicist known for her research on non-equilibrium thermodynamics, spin glass, and glassy systems. She works in France as a professor of physics at the Sorbonne University.
The Cugliandolo–Kurchan equations, two integro-differential equations describing the behavior of spin glass, are named for her and her coauthor Jorge Kurchan , another Argentine physicist, after their studies of these equations.[2][3]
