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, radiation, and anomalous dispersion at zero temperature           leftarrow          (BBT)
