In integrable systems in quantum field theory in (1+ 1)-dimensional space time and statistical
mechanical models on two-dimensional lattices, a central role is played by the Yang–Baxter …

A family of A 2 n (2) integrable open spin chains with U q (C n) symmetry was recently
identified in arXiv: 1702.01482. We identify here in a similar way a family of A 2 n− 1 (2) …

We present a new solution to the reflection equation associated with a coideal subalgebra of
U_q (A^(1) _ n-1) U q (A n-1 (1)) in the symmetric tensor representations and their dual …

We discuss a generalised version of Sklyanin's Boundary Quantum Inverse Scattering
Method applied to the spin-1/2, trigonometric sl (2) case, for which both the twisted-periodic …

We propose new families of solutions of the boundary Yang–Baxter equation. The open spin-
chain transfer matrices constructed with these K-matrices have quantum group symmetry …

We calculate, using the group theoretic approach to string theory, the tree and one loop
scattering of four open and closed arbitrary bosonic string states. In the limit of high energy …

A bstract Exact solution of the quantum integrable\({D} _2^{(2)}\) spin chain with generic
integrable boundary fields is constructed. It is found that the transfer matrix of this model can …

Two branches of integrable open quantum-group invariant quantum spin chains are known.
For one branch (), a complete Bethe ansatz solution has been proposed. However, the other …

The An− 1 Gaudin model with integrable boundaries specified by non-diagonal K-matrices
is studied. The commuting families of Gaudin operators are diagonalized by the algebraic …

We formulate a quantized reflection equation in which q-boson valued L and K matrices
satisfy the reflection equation up to conjugation by a solution to the Isaev–Kulish 3D …
