Forces from fluctuations in and out of equilibrium
(in QED and active matter)
Summary
I. Force from equilibrium fluctuations: Particles, radiation, Casimir force
II. Force from "active matter": Pressure, ratchets, and curving boundaries
III. Ratchet forces: Destruction of order, thermal non-equilibrium
IV. Near-field effects: Rytov formalism, hear transfer and force
V. Engine: Work, friction, efficiency 
VI. Dynamic Casimir phenomena: Friction, and anomalous dispersion at zero temperature 
(BBT)
