Erbe, Björn and Schliemann, John (2010) Unexpected systematic degeneracy in a system of two coupled Gaudin models with homogeneous couplings. J. Phys. A: Mathematical and Theoretical 43 (49), p. 2002.
We report an unexpected systematic degeneracy between different multiplets in an inversion symmetric system of two coupled Gaudin models with homogeneous couplings, as occurring for example in the context of solid state quantum information processing. We construct the full degenerate subspace (being of macroscopic dimension), which turns out to lie in the kernel of the commutator between the ...
