Query: A Novel Theory for High Temperature Superconductors considering
  Inhomogeneous Charge Distributions   We present a percolation theory for the high-$T_c$ oxides pseudogap and $T_c$
dependence on the hole level. The doping dependent inhomogeneous charge
structure is modeled by a distribution which may represent the stripe
morphology and yield a spatial distribution of local $T_c(r)$. The temperature
onset of spatial dependent superconducting gap is identified with the vanishing
of the pseudogap temperature $T^*$. The transition to a superconducting state
corresponds to the percolation threshold among regions of different $T_c$. As a
paradigm we use a Hubbard Hamiltonian with a mean field approximation to yield
a doping and temperature dependent superconducting d-wave gap. We show here
that this new approach reproduces the phase diagram, explains and gives new
insights on several experimental features of high-$T_c$ oxides.
