Query: Occupation-constrained interband dynamics of a non-hermitian two-band
  Bose-Hubbard Hamiltonian   The interband dynamics of a two-band Bose-Hubbard model is studied with
strongly correlated bosons forming single-site double occupancies referred to
as doublons. Our model for resonant doublon interband coupling exhibits
interesting dynamical features such as quantum Zeno effect, the generation of
states such as a two-band Bell-like state and an upper-band Mott-like state.
The evolution of the asymptotic state is controlled here by the effective
opening of one or both of the two bands, which models decay channels.
