Quantum group symmetry in sine-Gordon and affine Toda field theories on the half-line
Gustav W Delius, Niall J. MacKay
We consider the sine-Gordon and affine Toda field theories on the half-line with classically integrable boundary conditions, and show that in the quantum theory a remnant survives…

Boundary remnant of Yangian symmetry and the structure of rational reflection matrices
G. W. Delius, N. J. MacKay, B. J. Short
For the classical principal chiral model with boundary, we give the subset of the Yangian charges which remains conserved under certain integrable boundary conditions, and extract…

Coupling integrable field theories to mechanical systems at the boundary
P. Baseilhac, G. W. Delius
We present an integrable Hamiltonian which describes the sinh-Gordon model on the half line coupled to a non-linear oscillator at the boundary. We explain how we apply Sklyanin's f…
