Polarization correlation complete

The Bell states have a unique feature that all the information on polarization properties is completely contained in the (polarization-) correlations between the separate photons, while the individual particle does not have any polarization prior to measurement. In other words, all the information is distributed among two particles, and none of the individual systems carries any information. This is the essence of entanglement. At the same time, these (polarization-) correlations are stronger than allowed classically, since they violate bounds imposed by local realistic theories via the Bell-inequality [Bell 1964] or they lead to a maximal contradiction between such theories and quantum mechanics as signified by the Greenberger-Horne-Zeilinger theorem... [Pg.49]

Model peptides that could build up quarternary fibrillar structures are not yet known. Though complete explanation of the interdependence between the primary structure and the stability of the quarternary structure has not yet been possible, i.e. the role of the different amino acids in collagen could be understood completely only in correlation with the fibril formation (formation of polar and hydrophobic clusters ). [Pg.199]

One important stracture in molecules are polar bonds and, as a result, polar molecules. The polarity of molecules had been first formulated by the Dutch physicist Peter Debye (1884-1966) in 1912, as he tried to build a microphysical model to explain dielectricity (the behaviour of an electric field in a substance). Later, he related the polarity of molecules to the interaction between molecules and ions. Together with Erich Hiickel he succeeded in formulating a complete theory about the behaviour of electrolytes (Hofimann, 2006). The discovery of the dipole moment caused high efforts in the research on physical chemistry. On the one hand, methods for determining the dipole momerrt were developed. On the other hand, the correlation between the shape of the molectrle and its dipole moment was investigated (Estermanrr, 1929 Errera Sherrill, 1929). [Pg.233]

On the other hand, the analyst might not be interested in global retention indices. Indeed, by increasing the temperature for SF3, he would obtain similar retention indices as for the other two. He will then observe that the relative retention time, i.e. the retention times of the substances compared with each other, are the same for SF, and SF3 and different from SFj. Chemically, this means that SF3 has different polarity from SFj, but the same specific interactions. This is best expressed by using the correlation coefficient as the similarity measure. Indeed, rj3 = 1, indicating complete similarity, while r 2 23 much lower. Since both... [Pg.63]

Most FPA studies to date on DNA have lacked sufficient time resolution to observe directly the relaxation of the internal correlation functions. Instead, the initial anisotropy r0 is taken as an adjustable parameter. Equations (4.30) show that such a procedure is completely valid for anisotropic diffusors (i.e., (A ft)2 = (dx(t)2)), provided the rapid internal motion of the transition dipole is isotropic. It has not yet been ascertained whether the internal motion actually is isotropic, so this must be assumed.(83) A recent claim(86) that large amplitudes of polar wobble are required to fit both the small amplitude of initial FPA relaxation 87 and the linear dichroism88 has been refuted. 83j... [Pg.155]

Full ab initio electron-correlation methods, from MP2 to CCSD(T) (the acronyms refer to increasing complexity in the treatment of correlation, with increasing computational cost) include polarization and dispersion contributions and apply to any molecular system. Accuracy depends on the size of the basis set, but so-called complete set limit calculations can nowadays be carried out. [Pg.12]

Ivency or emulsification of beeswax, aqueous solubility, and vapor pressure are completely correlated with nematocidal efficacy as determined in laboratory tests. The correlation is not complete when field efficacy is considered. Thus carbon tetrachloride, benzene, and toluene should be good nematocides, but have not proved satisfactory in field tests. Likewise carbon disulfide, while a sound nematocide under optimum conditions, requires, for satisfactory nematode control, a greater quantity than would be expected on the basis of its solubilities and solvency. The answer may lie in the lack of polarity of these molecules. [Pg.95]
