Quantum contribution to domain wall tension from spectral methods
N. Graham, H. Weigel
In field theory, domain walls are constructed by embedding localized field configurations varying in one space dimension, such as the kink, in two or three space dimensions.…

Quantum energies of solitons with different topological charges
N. Graham, H. Weigel
The vacuum polarization energy is the leading quantum correction to the classical energy of a soliton. We study this energy for two-component solitons in one space dimension as a f…

One-Loop Quantum Stress-Energy Tensor for the Kink and sine-Gordon Solitons
Noah Graham, Herbert Weigel
We compute the renormalized one-loop quantum corrections to the energy density and pressure for solitons in the dimensional scalar sine-Gordon and kin…
