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+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 t…
A Finite Tension for the Domain Wall
Jarah Evslin, Hui Liu, Baiyang Zhang +1
In 1+1 dimensions, it is well known that the quantum states corresponding to solitons are well described by coherent states. In his 1975 Erice lectures, Coleman observed that this…
The Reflection Coefficient of a Reflectionless Kink
Jarah Evslin, Hui Liu
Classically, reflectionless kinks transmit all incident radiation. Recently, we have used an analyticity argument together with a solution of the Lippmann-Schwinger equation to wri…
