(Quantum) twisted Yangians: symmetry, Baxterisation and centralizers
Nicolas Crampe, Anastasia Doikou
Based on the (quantum) twisted Yangians, integrable systems with special boundary conditions, called soliton non-preserving (SNP), may be constructed. In the present article we foc…
Spectrum and Bethe ansatz equations for the U_ {q}(gl(N)) closed and open spin chains in any representation
D. Arnaudon, N. Crampe, A. Doikou +2
We consider the N-site U_{q}(gl(N)) integrable spin chain with periodic and open diagonal soliton-preserving boundary conditions. By employing analytical Bethe ansatz techniques we…
Analytical Bethe Ansatz for open spin chains with soliton non preserving boundary conditions
D. Arnaudon, N. Crampe, A. Doikou +2
We present an ``algebraic treatment'' of the analytical Bethe ansatz for open spin chains with soliton non preserving (SNP) boundary conditions. For this purpose, we introduce abst…
On sl(N) and sl(M|N) integrable open spin chains
D. Arnaudon, J. Avan, N. Crampe' +3
We study open spin chains based on rational sl(N) and sl(M|N) R-matrices. We classify the solutions of the reflection equations, for both the soliton-preserving and soliton-non-pre…
On osp(M|2n) integrable open spin chains
Daniel Arnaudon, Jean Avan, Nicolas Crampe +3
We consider open spin chains based on osp(m|2n) Yangians. We solve the reflection equations for some classes of reflection matrices, including the diagonal ones. Having then integr…
