dc.description.abstract	We adopt a t1-t2-t3-J-G model for explanation of x≈1/8 anomaly in HTSC compounds. The calculated charge susceptibility has a maximum near (π, π) leading to charge density wave (CDW) formation with the CDW amplitude eQ = x in very narrow band regime at intermediate temperatures and near (π, π/2) as temperature approaches zero. The in-phase domain structure as a candidate for "stripe" picture is proposed. We propose an experiment to apply pressure, and predict fast increase of Tc at anomalous value x≈1/ 8 in the presence of CDW. The enhancement of Tc will decline when CDW are suppressed by pressure. © 2004 Elsevier B.V. All rights reserved.
