    "abstract": "The spectrum of the Quantum Discrete Nonlinear Schr\\\"odinger equation on a\nperiodic 1D lattice shows some interesting detailed band structure which may be\ninterpreted as the quantum signature of a two-breather interaction in the\nclassical case. We show that this fine structure can be interpreted using\ndegenerate perturbation theory.",
