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…
Quantum stabilization of a hedgehog type of cosmic string
M. Quandt, N. Graham, H. Weigel
Within a slightly simplified version of the electroweak standard model we investigate the stabilization of cosmic strings by fermion quantum fluctuations. Previous studies of quant…
The Dirichlet Casimir Problem
N. Graham, R. L. Jaffe, V. Khemani +3
Casimir forces are conventionally computed by analyzing the effects of boundary conditions on a fluctuating quantum field. Although this analysis provides a clean and calculational…
