Exotic supersymmetry of the kinkantikink crystal, and the infinite period limit
Abstract
Some time ago, Thies et al. showed that the GrossNeveu model with a bare mass term possesses a kinkantikink crystalline phase. Corresponding selfconsistent solutions, known earlier in polymer physics, are described by a selfisospectral pair of onegap periodic Lame potentials with a Darboux displacement depending on the bare mass. We study an unusual supersymmetry of such a secondorder Lame system, and show that the associated firstorder Bogoliubovde Gennes Hamiltonian possesses its own nonlinear supersymmetry. The Witten index is ascertained to be zero for both of the related exotic supersymmetric structures, each of which admits several alternatives for the choice of a grading operator. A restoration of the discrete chiral symmetry at zero value of the bare mass, when the kinkantikink crystalline condensate transforms into the kink crystal, is shown to be accompanied by structural changes in both of the supersymmetries. We find that the infinite period limit may or may not change the index. We also explain the origin of the Darbouxdressing phenomenon recently observed in a nonperiodic selfisospectral onegap PoeschlTeller system, which describes the Dashen, Hasslacher, and Neveu kinkantikink baryons.
