Almost periodic localized states in a dilaton model

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Extremely long-living spatially localized oscillating states can be numerically observed in a theory where a massive real scalar field is coupled to a massless dilaton field. These objects are closely related both to at background oscillons and to general relativistic oscillatons. A small-amplitude expansion is applied to describe the core region, and the scaling properties are shown to be the same as those for oscillatons. The nonpertur- batively small energy loss rate is calculated by complex extension of the Fourier mode equations and applying Borel summation.
