16 Dec 2003 | | Journal: | Phys Rev Letts. 93, 025504 (2004) DOI: 10.1103/PhysRevLett.93.025504 | | Subject: | Quantum Physics; Soft Condensed Matter; Pattern Formation and Solitons | quant-ph cond-mat.soft nlin.PS | | Abstract: | The spectrum of the Quantum Discrete Nonlinear Schrödinger equation on a periodic 1D lattice shows some interesting detailed band structure which may be interpreted as the quantum signature of a two-breather interaction in the classical case. We show that this fine structure can be interpreted using degenerate perturbation theory. | | Source: | arXiv, quant-ph/0312143 | | Other source: | [GID 114561] pmid15323927 | | Services: | Forum | Review | PDF | Favorites | |
