Issues on magnon reflection
L. Palla
Two questions related to reflections of magnons in AdS/CFT are discussed: namely the problem of explaining the (physical) poles of the reflection amplitudes using Landau type diagr…
On the boundary form factor program
Z. Bajnok, L. Palla, G. Takacs
Boundary form factor axioms are derived for the matrix elements of local boundary operators in integrable 1+1 dimensional boundary quantum field theories using the analyticity prop…
Casimir force between planes as a boundary finite size effect
Z. Bajnok, L. Palla, G. Takacs
The ground state energy of a boundary quantum field theory is derived in planar geometry in D+1 dimensional spacetime. It provides a universal expression for the Casimir energy whi…
Finite size effects in quantum field theories with boundary from scattering data
Z. Bajnok, L. Palla, G. Takacs
We derive a relation between leading finite size corrections for a 1+1 dimensional quantum field theory on a strip and scattering data, which is very similar in spirit to the appro…
Some semi-classical issues in boundary sine-Gordon model
M. Kormos, L. Palla
The semi-classical quantisation of the two lowest energy static solutions of boundary sine-Gordon model is considered. A relation between the Lagrangian and bootstrap parameters is…
The spectrum of boundary sine-Gordon theory
Z. Bajnok, L. Palla, G. Takacs
We review our recent results on the on-shell description of sine-Gordon model with integrable boundary conditions. We determined the spectrum of boundary states by closing the boun…
