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…
Dual Separated Variables and Scalar Products
Nikolay Gromov, Fedor Levkovich-Maslyuk, Paul Ryan +1
Separation of variables (SoV) is an extremely efficient and elegant technique for analysing physical systems but its application to integrable spin chains was limited until recentl…
Classifying integrable spin-1/2 chains with nearest neighbour interactions
Marius de Leeuw, Anton Pribytok, Paul Ryan
We classify all fundamental integrable spin chains with two-dimensional local Hilbert space which have regular R-matrices of difference form. This means that the R-matrix underlyin…
