Look at George Jones' reply above, He is right, the link he has gives a very nice description of the whole negative energy argument.

rot raman If the polarizability is not anisotropic the polarizability will not change as the molecule rotates and you need this changing polarizability for the molecule to be active. This is similar to vibrational raman where the polarizability of the molecule must change as the molecule...

rotational raman An easier way to understand it might be to state that for a molecule to be rotationally Raman active, the polarizability perpendicular to the rotational axis should be anisotropic, or the polarizability should be different in different directions. This results in the...

lost energy Another way to think about it is that the particle that escapes carries away energy, so to obey conservation of energy, the particle that remains inside the event horizon has a negative energy if you will, this decreases the overall mass of the black hole causing it to get smaller...

quantum beginnings He reasoned if a EM radiation can be described as a wave and as a particle (photon). Then perhaps the analog it true and things that were originally described/discovered as particles can behave as waves. I think then the question was posed well then what is the wave...

photon pairs See Physics Today August 2005 pg. 20

pick up a book Given your background I would get a book on Modern physics or an intro book to quantum. Quantum Mechanics by Ohanian is a good intro. A book that is applied to spectroscopy might also be a good start because it applies QM directly to more tangible problems. Look at...

One more I like Understanding Quantum Mechanics by Roland Omnes Some math but not too heavy.

plasmons Plamons do occur in the visible. Think of the free electrons in a metal sloshing about like water in a bucket. If you shine tunable monochromatic light on the metal and scan the wavelength, at certain frequencies(wavelengths) there can be a collective excitation of these free...

photons Photons can and do occur in pairs. (Not that they have to.) Photons are their own antiparticles. The original inquiry regarded doing an experiment to see virtual particles. I was trying to give and example.

Hawking Radiation Hawking Radiation is a sort of experiment for observing virtual particles. If a photon pair is created from vacuum fluctuations on the event horizon of a black hole, the photon on the outside of the event horizon (virtual particle) will survive and be seen as radiation. The...
