  We study the emergence of the quantum spin Hall (QSH) states for the
pseudo-gap (PG) phase of Bi2212 bilayer system, assumed to be D-density
wave(DDW) ordered, starting with a strong Rashba spin-orbit coupling(SOC)
armed, and the time reversal symmetry (TRS) complaint Bloch Hamiltonian. The
presence of strong SOC gives rise to non-trivial, spin-momentum locked spin
texture tunable by electric field. The emergence of quantum anomalous Hall
effect with TRS broken Chiral DDW Hamiltonian of Das Sarma et al. is found to
be possible.
