Query: Intrinsically coupled stripes within the CuO2 planes of high-Tc
  materials   Analysis of the electronic state of the CuO2 planes of high-Tc materials has
been performed with special regard to the influence of the Coulomb interactions
separated after moments. Different symmetry breaking effects were revealed. A
commensurate charge and bonding fluctuation state (CBF) with the period (2a,2b)
is established which exists collinearly with the antiferromagnetic spin state.
The CBF state and the antiferromagnetic spin state are result of the same
electronic renormalizations. The existence of localized topological hole states
under hole doping is established. As a consequence of this local symmetry is
broken. A quadrupolar-polarization induced attractive hole-hole interaction can
exist between such topological hole states. This interaction creates an ordered
topological hole structure which leads to a global symmetry breaking. The
ordered topological hole structure (b-holes) can be characterized as parallel
one-dimensional electronic states (stripes) along particular ..Cu-O-Cu..
bonding directions being intrinsically coupled to each other. The b-hole state
exists undisturbed for hole concentrations n in the range of 0.125 <= n <= 0.25
holes/copper. In addition to b-holes, holes which are not intrinsically bonded
exist (f-holes) for hole concentrations of n > 0.125 holes/copper. The
inevitable consequence is an electronic two fluid behaviour (b-holes, f-holes)
within the range of 0.125 < n <= 0.25 holes/copper. A comparison with
experimental results is given with particular respect to mySR, neutron
scattering (1/8 problem), Hall-effect anomalies and scanning tunneling
microscopy (STM).
