Form factors of the half-infinite XXZ spin chain with a triangular boundary

open access: yes, 2014
The half-infinite XXZ spin chain with a triangular boundary is considered in the massive regime. Two integral representations of form factors of local operators are proposed using bosonization.

Externally driven one-dimensional Ising model

open access: yes, 2012
A one dimensional kinetic Ising model at a finite temperature on a semi-infinite lattice with time varying boundary spins is considered. Exact expressions for the expectation values of the spin at each site are obtained, in terms of the time dependent ...

Solving the Coulomb scattering problem using the complex scaling method

open access: yes, 2009
Based on the work of Nuttall and Cohen [Phys. Rev. {\bf 188} (1969) 1542] and Resigno et al{} [Phys. Rev. A {\bf 55} (1997) 4253] we present a rigorous formalism for solving the scattering problem for long-range interactions without using exact ...

Integrable lattice realizations of conformal twisted boundary conditions

open access: yesPhysics Letters B, 2001
We construct integrable realizations of conformal twisted boundary conditions for ^sl(2) unitary minimal models on a torus. These conformal field theories are realized as the continuum scaling limit of critical A-D-E lattice models with positive spectral parameter. The integrable seam boundary conditions are labelled by (r,s, ) in (A_{g-2},A_{g-1}, )
