Energy Density and Pressure in Power-wall Models

Abstract

A finite ultraviolet cutoff near a reflecting boundary yields a stress tensor that violates the basic energy-pressure relation. Therefore, a " soft " wall described by a power-law potential , which needs no ad hoc cutoff, is being investigated by the collaboration centered at Texas A&M University and the University of Oklahoma. Progress is reported here. 1.1. Basic formalism and empty space We model the electromagnetic vacuum-energy problem by a massless scalar field in three space dimensions, subjected to the Dirichlet boundary condition on the " conducting " boundaries. The vacuum energy can be calculated from a Green function, such as the " cylinder kernel " ,
