Transient Casimir Forces

from Quenches in Thermal and Active Matter


Summary

I.      Casimir Forces:         

Long-range correlations lead to long-range fluctuation-induced forces.

II.   Transient FIF:                   

Agitating a conserved density leads to transient long-ranged forces.

III.   Simulations

yellow ball  Changes in the mean density cause transient forces:             

yellow ball  FIF component (for interacting particles) at long times:
