Query: Superconductivity in the background of two-dimensional stripe
  superstructure   I propose a superconductivity model, which is based on the assumption that
stripes in high-Tc cuprates (a) exist and (b) organize themselves in a
two-dimensional superstructure. The model describes hole states, which are
localized either inside the stripes or in the antiferromagnetic domains between
the stripes. The superconductivity in this model emerges due to the
interaction, which is, presumably, mediated by the transverse fluctuations of
stripes. The tunnelling density of states obtained from the mean field solution
of the model is asymmetric with respect to the chemical potential, has Van Hove
singularity identified as a superconducting peak, and, in one of the model
regimes, has linear functional form in the vicinity of the chemical potential.
The relation between the critical temperature and the zero-temperature
superfluid density has ``fish-like'' form, which quantitatively resembles
experimental data. The superconducting order parameter obtained from this model
has two components exhibiting non-trivial phase and sign change under
translations in real space.
