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.
