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 ...
WebJul 15, 2024 · The so-called fluctuation-dissipation relation deeply connects a system's intrinsic fluctuations on the one hand with the way how it dissipates energy imparted from an external stimulus on the other. Yet, despite being one of the fundamental concepts of statistical mechanics, it has never been directly certified in a quantum system. ...
