surface plasmon??

hi
Can anyone explain to me what's the surface plasmon?
thanks
 
Physics news on Phys.org


Its a collective oscillation of the electron density in a metal. It's most prominent in Au, Ag, and Cu, possibly due to the low imaginary part of the dielectric constant which means that the oscillations are more pronounced and less dampened.
 


What excalibur described is any plasmon - the vibrational eigenmode of the entire electron gas about the positive lattice. A surface plasmon is specifically that mode which propagates along the surface of a metal or the interface between two.
 

Thread 'Stability of persistent currents in superconductors regardless of temperature'

From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...

Thread 'Instantaneous dipole moment and orbitals'

Hi. I have got question as in title. How can idea of instantaneous dipole moment for atoms like, for example hydrogen be consistent with idea of orbitals? At my level of knowledge London dispersion forces are derived taking into account Bohr model of atom. But we know today that this model is not correct. If it would be correct I understand that at each time electron is at some point at radius at some angle and there is dipole moment at this time from nucleus to electron at orbit. But how...
