Quantum Lifts of Noninteger Power Law Field Theories
Jarah Evslin, Hengyuan Guo, Stefano Bolognesi
Field theories whose potentials have noninteger power laws have found many applications, but are often claimed to have no lift to quantum field theory except as effective model…
(De-)Exciting the Third Poschl-Teller Kink
Hengyuan Guo, Jarah Evslin, Stefano Bolognesi
There is a series of scalar models possessing reflectionless kinks whose linear perturbations are described by a Pöschl-Teller potential at integer level . The cases an…
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…
(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…
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…
