Perspective on “Statistical mechanical theory of irreversible processes. I. General theory and simple applications to magnetic and conduction problems” [Kubo R (1957) J Phys Soc Jpn 12: 570]
Kubo’s paper on linear-response theory provided a unified language to describe a wide variety of transport phenomena, both quantum and classical, in a suitable “microscopic” language. The paper has been crucial for subsequent developments in numerical simulation.
