Lineshape predictions via Bethe ansatz for the one-dimensional spin-1/2 Heisenberg antiferromagnet in a magnetic field
Michael Karbach, Gerhard Muller
The spin fluctuations parallel to the external magnetic field in the ground state of the one-dimensional (1D) s=1/2 Heisenberg antiferromagnet are dominated by a two-parameter set…

Integrability and action operators in quantum Hamiltonian systems
Vyacheslav V. Stepanov, Gerhard Muller
For a (classically) integrable quantum mechanical system with two degrees of freedom, the functional dependence of the Hamiltonian operator on th…

Signatures of quantum integrability and nonintegrability in the spectral properties of finite Hamiltonian matrices
Vyacheslav V. Stepanov, Gerhard Muller
For a two-spin model which is (classically) integrable on a five-dimensional hypersurface in six-dimensional parameter space and for which level degeneracies occur exclusively (wit…
