One-Point Functions of N=2 Super-Liouville Theory with Boundary
Changrim Ahn, Marian Stanishkov, Masayoshi Yamamoto
We derive one-point functions of the N=2 super-Liouville theory on a half line using the modular transformations of the characters in terms of the bulk and boundary cosmological co…
Excited states NLIE for sine-Gordon model in a strip with Dirichlet boundary conditions
Changrim Ahn, Marco Bellacosa, Francesco Ravanini
We investigate various excited states of Sine-Gordon model on a strip with Dirichlet boundary conditions on both boundaries using a Non Linear Integral Equation (NLIE) approach.
Boundary Action of N=2 Super-Liouville Theory
Changrim Ahn, Masayoshi Yamamoto
We derive a boundary action of N=2 super-Liouville theory which preserves both N=2 supersymmetry and conformal symmetry by imposing explicitly and . The re…
Finite size effects in the XXZ and sine-Gordon models with two boundaries
Changrim Ahn, Rafael I. Nepomechie
We compute the boundary energy and the Casimir energy for both the spin-1/2 XXZ quantum spin chain and (by means of the light-cone lattice construction) the massive sine-Gordon mod…
Excited TBA Equations II: Massless Flow from Tricritical to Critical Ising Model
Paul A. Pearce, Leung Chim, Changrim Ahn
We consider the massless tricritical Ising model M(4,5) perturbed by the thermal operator in a cylindrical geometry and apply integrable boundary conditions, labelled by the Kac la…
