Resonant invisibility with finite range interacting fermions
arXiv:1106.4483 · doi:10.1016/j.physleta.2011.11.048
Abstract
We study the eigenstates of two opposite spin fermions on a one-dimensional lattice with finite range interaction. The eigenstates are projected onto the set of Fock eigenstates of the noninteracting case. We find antiresonances for symmetric eigenstates, which eliminate the interaction between two symmetric Fock states when satisfying a corresponding selection rule.
