Introduction to the Bethe Ansatz I
... In 1931 Hans Bethe2 presented a method for obtaining the exact eigenvalues and eigenvectors of the onedimensional (1D) spin-1/2 Heisenberg model, a linear array of electrons with uniform exchange interaction between nearest neighbors. Bethe’s parametrization of the eigenvectors, the Bethe ansatz, ha ...

The physical significance of the concept, which I here call GMW-entanglement, is enshrined in three biconditionals the analogues of which hold for the standard concept of entanglement for “distinguishable” systems; i.e. systems for which permutation invariance is not imposed.
