Relativistic Wigner Function, Charge Variable and Structure of Position Operator | | B.I. Lev

20 Dec 2001 | | Subject: | quant-ph | | Abstract: | The relativistic phase-space representation by means of the usual position and momentum operators for a class of observables with Weyl symbols independent of charge variable (i.e. with any combination of position and momentum) is proposed. The dynamical equation coincides with its analogue in the non-local theory (generalization of the Newton-Wigner position operator approach) under conditions when particles creation is impossible. Differences reveal themselves in specific constraints on possible initial conditions. | | Source: | arXiv, quant-ph/0112122 | | Services: | Forum | Review | PDF | Favorites | |
