A Q-operator for open spin chains II: boundary factorization
Alec Cooper, Bart Vlaar, Robert Weston
One of the features of Baxter's Q-operators for many closed spin chain models is that all transfer matrices arise as products of two Q-operators with shifts in the spectral paramet…
A Q-operator for open spin chains I: Baxter's TQ relation
Bart Vlaar, Robert Weston
We construct a Q-operator for the open XXZ Heisenberg quantum spin chain with diagonal boundary conditions and give a rigorous derivation of Baxter's TQ relation. Key roles in the…
Solutions of the reflection equations
Vidas Regelskis, Bart Vlaar
We find the complete set of invertible solutions of the untwisted and twisted reflection equations for the Bazhanov-Jimbo R-matrix of type . We also show t…
Reflection matrices, coideal subalgebras and generalized Satake diagrams of affine type
Vidas Regelskis, Bart Vlaar
We present a generalization of the theory of quantum symmetric pairs as developed by Kolb and Letzter. We introduce a class of generalized Satake diagrams that give rise to (not ne…
A non-symmetric Yang-Baxter algebra for the quantum nonlinear Schrödinger model (PhD Thesis)
Bart Vlaar
We study certain non-symmetric wavefunctions associated to the quantum nonlinear Schrödinger (QNLS) model, introduced by Komori and Hikami using representations of the degenerate a…
A non-symmetric Yang-Baxter Algebra for the Quantum Nonlinear Schrödinger Model
Bart Vlaar
We study certain non-symmetric wavefunctions associated to the quantum nonlinear Schrödinger model, introduced by Komori and Hikami using Gutkin's propagation operator, which invol…
