  The (Cu)13-BEC model of high-temperature superconductivity was previously
shown to account for many of the principal thermodynamic and electronic
properties of the superconducting cuprates. Here I show that this model is also
able to account for many of the key characteristics of the coupled CDW and SDW
orders in these compounds. These include the general coexistence of metallic
parallel stripes with superconductivity, the well-known linear relationship
between the incommensurability of the SDW-induced IC magnetic peaks and the
dopant concentration, as well as the saturation of this incommensurabilty at a
value of about 1/8 for doping greater than 1/8. The model also provides a
natural explanation for the celebrated 1/8-anomaly in LSCO and LBCO. It is also
able to account for the severe suppression of the superconductivity in LNSCO at
all doping levels and for the variations in the properties of LBSCO, at a fixed
hole doping of 1/8, as its crystal structure is changed. Furthermore, the
(Cu)13-BEC model is also consistent with many of the characteristics of the SDW
orders in Y123. Most importantly, scanning tunneling microscopy results on
Bi2212 appear to provide a direct validation of the CDW order predicted by the
model.
