Boundary Spectrum in the sine-Gordon Model with Dirichlet Boundary Conditions
نویسندگان
چکیده
We find the spectrum of boundary bound states for the sine-Gordon model with Dirichlet boundary conditions, closing the bootstrap and providing a complete description of all the poles in the boundary reflection factors. The boundary Coleman-Thun mechanism plays an important role in the analysis. Two basic lemmas are introduced which should hold for any 1+1-dimensional boundary field theory, allowing the general method to be applied to other models.

Boundary bound states and boundary bootstrap in the sine-Gordon model with Dirichlet boundary conditions
We present a complete study of boundary bound states and related boundary Smatrices for the sine-Gordon model with Dirichlet boundary conditions. Our approach is based partly on the bootstrap procedure, and partly on the explicit solution of the inhomogeneous XXZ model with boundary magnetic field and of the boundary Thirring model. We identify boundary bound states with new “boundary strings” ...
متن کاملAnalytical solutions for the fractional Klein-Gordon equation
In this paper, we solve a inhomogeneous fractional Klein-Gordon equation by the method of separating variables. We apply the method for three boundary conditions, contain Dirichlet, Neumann, and Robin boundary conditions, and solve some examples to illustrate the effectiveness of the method.
متن کاملSolution of the Dirichlet boundary value problem for the Sine-Gordon equation
The sine-Gordon equation in light cone coordinates is solved when Dirichlet conditions on the L-shape boundaries of the strip {t ∈ [0, T ]} ∪ {x ∈ [0,∞]} are prescribed in a class of functions that vanish (mod 2π) as x → ∞ at initial time. The method is based on the inverse spectral transform (IST) for the Schrödinger spectral problem on the semi-line x > 0 solved as a Hilbert boundary value pr...
متن کاملExact solution of a massless scalar field with a relevant boundary interaction
We solve exactly the “boundary sine-Gordon” system of a massless scalar field φ with a cosβφ/2 potential at a boundary. This model has appeared in several contexts, including tunneling between quantum-Hall edge states and in dissipative quantum mechanics. For β < 8π, this system exhibits a boundary renormalization-group flow from Neumann to Dirichlet boundary conditions. By taking the massless ...
متن کاملA ug 2 00 1 THE SPECTRUM OF BOUNDARY SINE - GORDON THEORY ∗
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 boundary bootstrap and gave a derivation of Al.B. Zamolodchikov's (unpublished) formulae for the boundary energy and the relation between the Lagrangian (ultraviolet) and bootstrap (infrared) parameters. These results hav...
