Query: Two electron entanglement in quasi-one dimensional system: Role of
  resonances   We analyze the role of resonances in two-fermion entanglement production for
a quasi one-dimensional two channel scattering problem. We solve exactly for
the problem of a two-fermion antisymmetric product state scattering off a
double delta well potential. It is shown that the two-particle concurrence of
the post-selected state has an oscillatory behavior where the concurrence
vanishes at the values of momenta for virtual bound states in the double well.
These concurrence zeros are interpreted in terms of the uncertainty in the
knowledge of the state of the one particle subspace reduced one particle
density matrix. Our results suggest manipulation of fermion entanglement
production through the resonance structure of quantum dots.
