Abstract

A class of functions whose relativistic evolution is analytically solvable is found. These wave functions are initially localized (by a Newton-Wigner definition) and their spreading through time is investigated. Using these wave packets an explicit example of the violation of relativistic causality (in the spirit of Hegerfeldts theorem) is presented. Some detailed qualitative features of relativistic quantum behavior are displayed.
