Polarization statistics
... To complete the analysis of polarization statistics beyond the quantum Q function we have considered other possibilities. More specifically we have studied the so called s-ordered distributions for the complex amplitudes that depend on a real parameter s including the Q function as the case s 1, ...

Photoemission studies of quantum well states in thin films
... The ®rst photoemission observation of quantum size effects was reported in 1986 [18]. The evidence was clear but the quantum well peaks were very broad, again due to ®lm roughness. Later work, however, clearly established the importance of quantum size effects in ®lms [19±25]. The argument that phot ...
