polariton, polaron, plasmon and spaser

ebol

Hello everyone!
I would like to ask you for help on this:
1. what are the differences between polariton, polaron and plasmon?
2. such as theoretical aspects I have to know to understand the functioning of a spaser?

(spaser=surface plasmon amplification by stimulated emission of radiation)

thanks for the help!

p.s.
if you have any books, articles or links to advise me, you would help me twice.
see you soon!

Have you tried using Google to get some initial information on those terms? It would help if you could do some initial reading on your own first, and then ask specific questions about that reading here afterwards...

Hi!
I read several articles about the spaser, including
Bergman D.J. et al., 2003
Stockman M.I., 2008
Oulton R.F. et al., 2009

I read several articles about the plasmons, including
Barnes W.L. et al., 2003
Stockman M.I., 2011

Also, I have the basics of physics ... but I can not seem to connect the different parts of what I already know. I do not have a vision of the whole:
For example, I have to study the Drude model? or Raman scattering? etc.
I do not have a clear idea of ​​what I need from all that I have studied :/
