\(F_T=\cfrac{T_aT_b}{4\pi\tau_or^2}\)
could also be the reason why some reported material can go transparent on the flick of a switch.
Basically you have resonance pulsed micro-magnetic coils to cool the material rapidly. Photons pass through without being repulsed and the material is see-through. Some photons are absorbed, but since most of the structural lattice is space, light will pass through only slightly dimmed.
