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
Changes in the mean density cause transient forces:
FIF component (for interacting particles) at long times:
