An Extended Soliton's Zero Modes
Jarah Evslin, Hui Liu
Quantum field theory in the presence of localized solitons is more complicated than vacuum sector quantum field theory, largely as a result of the soliton's zero modes. In the pres…

The Domain Wall String's Anti-Stokes Scattering Cross Section
Hengyuan Guo, Jarah Evslin, Hui Liu
We consider anti-Stokes scattering, in which a perturbative meson scatters off of a domain wall string's shape mode excitation, de-exciting it. Previously the probability of this p…

Scheme Dependence of the One-Loop Domain Wall Tension
Jarah Evslin, Hui Liu
The one-loop tension of the domain wall in the 3+1 dimensional double-well model was derived long ago using dimensional regularization. The methods used can only be applied t…
