Coarse-grained second-order response theory
While linear response theory, manifested by the fluctuation dissipation theorem, can be applied at any level of coarse-graining, nonlinear response theory is fundamentally of a microscopic nature. For perturbations of equilibrium systems, we develop an exact theoretical framework for analyzing the n...
