I read a paper about coherent surface plasmon amplification by free electron pumping in an article a few days ago. It seems to work as some kind of free electron laser-like light source, and I wonder how high the energy of photons can go in this way. Also I read in another paper about "efficient" generation of "Extremely brilliant" and "collimated" MeV to GeV gamma rays in the plasma accelerator. I wonder if plasmonics can replace ionized gas to achieve this. There is indeed an idea of Plasmonic acceleration, right?

Plasmons on metal surfaces, as far as I know, usually have energies in the range of 10 to 100 eV. That's more like visible light.
 
The plasma frequency of metals is in the UV, not in the gamma ray range. GeV electrons can only produce incoherent bremsstrahlung.
 
Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
