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…
Luscher's mu-term and finite volume bootstrap principle for scattering states and form factors
B. Pozsgay
We study the leading order finite size correction (Luscher's mu-term) associated to moving one-particle states, arbitrary scattering states and finite volume form factors in 1+1 di…
Small amplitude quasi-breathers and oscillons
Gyula Fodor, Péter Forgács, Zalán Horváth +1
Quasi-breathers (QB) are time-periodic solutions with weak spatial localization introduced in G. Fodor et al. in Phys. Rev. D. 74, 124003 (2006). QB's provide a simple description…
Casimir effect in the boundary state formalism
Z. Bajnok, L. Palla, G. Takacs
Casimir effect in the planar setting is described using the boundary state formalism, for general partially reflecting boundaries. It is expressed in terms of the low-energy degree…
Boundary form factors in finite volume
M. Kormos, G. Takacs
We describe the volume dependence of matrix elements of local boundary fields to all orders in inverse powers of the volume. Using the scaling boundary Lee-Yang model as testing gr…
NLIE of Dirichlet sine-Gordon Model for Boundary Bound States
Changrim Ahn, Zoltan Bajnok, Laszlo Palla +1
We investigate boundary bound states of sine-Gordon model on the finite-size strip with Dirichlet boundary conditions. For the purpose we derive the nonlinear integral equation (NL…
