As far as I have understood, surface plasmon can't be excited with natural light because the dispersion relation of the plasmon doesn't cross the vacuum dispersion relation of light.
But, when we decrease the size (for example, we take a nanoparticle), we are now in quasistatic approximation...
Hello everybody.
I am trying to understand better what happens at a liquid-gas phase transition for the Van Der Waals model.
From what I have understood, from the Van Der Waals model we are able to plot the curve P(V) and to calculate the free energy F. Here are such curves :
Then, we...
