Abstract
We compute semiclassical corrections to the energy density of kinks in theory and of solitons in the sine-Gordon model in dimensions, using local and covariant renormalization techniques from quantum field theory in curved spacetimes. For the semiclassical correction to the energy, we recover the known results. Our analysis highlights a subtlety in the definition of a conserved stress tensor for scalar field theories in dimension.
