Query: Possible three-dimensional chiral charge ordered superconducting state
  in cuprates   The 2D pair-condensate is characterized by a fluctuating chiral charge
ordered state with a "checkerboard" pattern in the CuO_2 planes and with an
alternating supermodulation along the c-axis in such a way that the adjacent
layers are mirror images of one anothers electronic state. Planar chiral order
is revealed with a recent circular dichroism (CD) ARPES experiment (A.
Kaminski, et al., Nature, 416, 611. (2002)). We propose further CD experiments
on ultrathin films with varying thickness and argue that the odd number of unit
cells along the c-axis might provide dichroism hence might support the picture
of 3D chirality in cuprates. We find that Coulomb energy gain occurs along the
c-axis within a multilayer chiral charge ordered state, which is proportional
to the measured bilayer condensation energy and to $T_c$ at optimal doping.
Within our approach the superconducting (SC) pair is composed of the hole
content of the coherence area and the self-repulsion of the condensate is
compensated by the gain in the inter-layer Coulomb energy below $T_c$. The SC
condensate and the fluctuating charge order can also be described by a
dynamical inter-layer electrostatic complementarity.
