What does Landau damping lead to in metallic nanoparticles stimulated by EM wave?

1.What is the physical meaning of Landau damping? P.S. as far as I know, It is a kind of damping without collision but it has something to do with absorption. 2.If it is related to absorption...

Why is density of photons in Plasmonic and Metamaterial(P&M) nanostructures much higher than in free space?

In surface plasmon on the nanoparticles, the density of photons is much higher than in free space. I saw an articles saying that it is because the electrons which are in high density couple into...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
