Exicted Baryons in Large Nc QCD:
... • In practice, the method is very powerful as a quantitative tool for some quantities. • For these quantities the virtues of a model-independent approach are quite evident. • However, the method may be of little practicle if there are scales in the problem arising from physics other than 1/Nc ...

But we do care if the average dipole moment varies over large, macroscopic distances. For example, the density n may be larger in some parts of th ...

... around threshold indicates that the dephasing time due to polariton-polariton scattering is shorter than the polariton lifetime by a factor 2 (not shown). Such a mechanism could indeed permit attainment of internal thermal equilibrium before the escape of polaritons out of the microcavity. The criti ...
