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…
The Domain Wall Soliton's Tension
Jarah Evslin, Hui Liu, Baiyang Zhang
We calculate the one-loop tension of the domain wall soliton in the double-well model. Our result agrees with previous results from Dashen, Hasslacher and Neveu (1974) in 1+…
(Anti-)Stokes Scattering on the Domain Wall String
Hengyuan Guo, Hui Liu, Jarah Evslin
In a general (2+1)-dimensional scalar model, we consider the scattering of a single quantum of radiation off a domain wall string, which excites or de-excites the wall's internal s…
Constructing A Finite Tension Domain Wall in
Jarah Evslin, Hengyuan Guo, Hui Liu +1
We have recently claimed that the domain wall in the 3+1 dimensional double-well model can be constructed as a squeezed, coherent state and that at one loop it has a finite…
