Abstract

We compute the renormalized one-loop quantum corrections to the energy density T₀₀(x) and pressure T₁₁(x) for solitons in the 1+1 dimensional scalar sine-Gordon and kink models. We show how precise implementation of counterterms in dimensional regularization resolves previously identified discrepancies between the integral of T₀₀(x) and the known correction to the total energy.
