Current Algebras and QP Manifolds
Noriaki Ikeda, Kozo Koizumi
Generalized current algebras introduced by Alekseev and Strobl in two dimensions are reconstructed by a graded manifold and a graded Poisson brackets. We generalize their current a…
Exact spectrum of the XXZ open spin chain from the q-Onsager algebra representation theory
P. Baseilhac, K. Koizumi
The transfer matrix of the XXZ open spin-1/2 chain with general integrable boundary conditions and generic anisotropy parameter (q is not a root of unity and |q|=1) is diagonalized…
A deformed analogue of Onsager's symmetry in the XXZ open spin chain
P. Baseilhac, K. Koizumi
The XXZ open spin chain with general integrable boundary conditions is shown to possess a q-deformed analogue of the Onsager's algebra as fundamental non-abelian symmetry which ens…
N=2 boundary supersymmetry in integrable models and perturbed boundary conformal field theory
P. Baseilhac, K. Koizumi
Boundary integrable models with N=2 supersymmetry are considered. For the simplest boundary N=2 superconformal minimal model with a Chebyshev bulk perturbation we show explicitly h…
Sine-Gordon quantum field theory on the half-line with quantum boundary degrees of freedom
P. Baseilhac, K. Koizumi
The sine-Gordon model on the half-line with a dynamical boundary introduced by Delius and one of the authors is considered at quantum level. Classical boundary conditions associate…
