定常加速度系での量子論における局在性

Abstract

We construct states localized at a point on stationary coordinate systems in the at space- time. In a inertial system two kinds of localized states have been proposed by Newton-Wigner and Philips, respectively. These states are interpreted from the point of view of the quantum eld theory based on the particle picture and extended to stationary coordinate systems. In the Rindler coordinates and the Born coordinates, especially, localization of the Newton-Wigner states is checked by explicit calculation.
