| Summary: | The distribution of Bethe roots, solution of the inhomogeneous Bethe
equations, which characterize the ground state of the periodic XXX Heisenberg
spin-$\frac{1}{2}$ chain is investigated. Numerical calculations show that,
for this state, the new inhomogeneous term does not contribute to the Baxter
T-Q equation in the thermodynamic limit. Different families of Bethe roots are
identified and their large N behaviour are conjectured and validated. |
