Spin chains with boundary inhomogeneities
Rafael I. Nepomechie, Ana L. Retore
We investigate the effect of introducing a boundary inhomogeneity in the transfer matrix of an integrable open quantum spin chain. We find that it is possible to construct a local…
Yang-Baxter and the Boost: splitting the difference
Marius de Leeuw, Chiara Paletta, Anton Pribytok +2
In this paper we continue our classification of regular solutions of the Yang-Baxter equation using the method based on the spin chain boost operator developed in \cite{deLeeuw:201…
Free Fermions, vertex Hamiltonians, and lower-dimensional AdS/CFT
Marius de Leeuw, Chiara Paletta, Anton Pribytok +2
In this paper we first demonstrate explicitly that the new models of integrable nearest-neighbour Hamiltonians recently introduced in PRL 125 (2020) 031604 satisfy the so-called fr…
Classifying nearest-neighbour interactions and deformations of AdS
Marius de Leeuw, Chiara Paletta, Anton Pribytok +2
We classify all regular solutions of the Yang-Baxter equation of eight-vertex type. Regular solutions correspond to spin chains with nearest-neighbour interactions. We find a total…
New integrable 1D models of superconductivity
Marius de Leeuw, Anton Pribytok, Ana L. Retore +1
In this paper we find new integrable one-dimensional lattice models of electrons. We classify all such nearest-neighbour integrable models with su(2)xsu(2) symmetry following the p…
Towards the solution of an integrable spin chain
Rafael I. Nepomechie, Rodrigo A. Pimenta, Ana L. Retore
Two branches of integrable open quantum-group invariant quantum spin chains are known. For one branch (epsilon=0), a complete Bethe ansatz solution has been propose…
