Eigenvectors of open XXZ and ASEP models for a class of non-diagonal boundary conditions
Nicolas Crampé, Eric Ragoucy, Damien Simon
We present a generalization of the coordinate Bethe ansatz that allows us to solve integrable open XXZ and ASEP models with non-diagonal boundary matrices, provided their parameter…
Coordinate Bethe Ansatz for Spin s XXX Model
Nicolas Crampé, Eric Ragoucy, Ludovic Alonzi
We compute the eigenfunctions and eigenvalues of the periodic integrable spin s XXX model using the coordinate Bethe ansatz. To do so, we compute explicitly the Hamiltonian of the…
Universal Low Temperature Asymptotics of the Correlation Functions of the Heisenberg Chain
Nicolas Crampé, Frank Göhmann, Andreas Klümper
We calculate the low temperature asymptotics of a function that generates the temperature dependence of all static correlation functions of the isotropic Heisenberg chain.
