The Massive Klein-Gordon Field Coupled to a Harmonic Oscillator at the Boundary
A. George
We consider the massive Klein-Gordon field on the half line with and without a Robin boundary potential.The field is coupled at the boundary to a harmonic oscillator.We solve the s…
From Defects to Boundaries
Z. Bajnok, A. George
In this paper we describe how relativistic field theories containing defects are equivalent to a class of boundary field theories. As a consequence previously derived results for b…
Quantum group symmetry of integrable models on the half-line
Gustav W Delius, Alan George
This contribution to the Proceedings of the Workshop on Integrable Theories, Solitons and Duality in Sao Paulo in July 2002 summarizes results from the papers hep-th/0112023 and ma…
Quantum affine reflection algebras of type d_n^(1) and reflection matrices
Gustav W. Delius, Alan George
Quantum affine reflection algebras are coideal subalgebras of quantum affine algebras that lead to trigonometric reflection matrices (solutions of the boundary Yang-Baxter equation…
Coupling the Sine-Gordon Field Theory to a Mechanical System at the Boundary
P. Baseilhac, G. W. Delius, A. George
We describe an integrable system consisting of the sine-Gordon field, restricted to the half line, and coupled to a non-linear oscillator at the boundary. By extension of the coupl…
