Irreversibility in Quantum Field Theory
It is shown how the programme of decoherence can be applied in the context of quantum field theory. To illustrate the role of gauge invariance, we first discuss the charge superselection rule in quantum electrodynamics in some detail. We then present an example where macroscopic electromagnetic fields are “measured” through interaction with charges and thereby rendered classical. A central role...
متن کاملRandomness and Irreversibility in Quantum Field Theory
Randomness and Irreversibility in Quantum Field Theory. J. Pérez–Mercader Laboratorio de Astrof́ısica Espacial y F́ısica Fundamental Apartado 50727 28080 Madrid Quantum fluctuations, through quantum corrections, have the potential to lead to irreversibility in quantum field theory. We consider the virtual “charge” distribution generated by quantum corrections in the leading log, short range appro...
متن کاملIrreversibility and Higher-spin Conformal Field Theory
I discuss the properties of the central charges c and a for higher-derivative and higher-spin theories (spin 2 included). Ordinary gravity does not admit a straightforward identification of c and a in the trace anomaly, because it is not conformal. On the other hand, higherderivative theories can be conformal, but have negative c and a. A third possibility is to consider higher-spin conformal f...
متن کاملthe relationship between field-related cognitive styles and global reading comprehension of hypertext
this study investigates the relationship between field-related cognitive styles and global reading comprehension of hypertext. technically, field dependency is prevailing dominance of field on perception of parts, while global comprehension is skim-like reading to grasp the general content. in this research project, 60 senior and junior students of arak university majoring in english literature...
15 صفحه اولPulsed-field studies of the magnetization reversal in molecular nanomagnets
We report experimental studies of crystals of Mn12 molecular magnetic clusters in pulsed magnetic fields with sweep rates up to 43103 T/s. The steps in the magnetization curve are observed at fields that are shifted with respect to the resonant field values. The shift systematically increases as the rate of the field sweep goes up. These data are consistent with the theory of the collective dip...
