The Kramers Kronig relations are simply the statement that the function is causal in the time domain, or specially the function in the time domain has the form. ϵ ( t) = θ ( t) f ( t) Where f ( t) is some function of time, and θ is the Heaviside theta function, which is zero for negative times. Physically this means that the dielectric ...

WebJan 5, 2024 · The fluctuation–dissipation relations (FDR) played a pivotal role in the development of non-equilibrium statistical mechanics. Starting from the regime of weak departure from equilibrium, with the pioneering work of Einstein on mobility–diffusivity relation, through the central work of Onsager on the reciprocal relations [], a unification … In physics (specifically, the kinetic theory of gases), the Einstein relation is a previously unexpected connection revealed independently by William Sutherland in 1904, Albert Einstein in 1905, and by Marian Smoluchowski in 1906 in their works on Brownian motion.
