Vortex State in Na_xCoO_2.yH_2O: p_x\pm ip_y-wave versus d_{x^2-y^2}\pm id_{xy}-wave Pairing

Qiang Han, Z. D. Wang, Q. -H. Wang +1

Based on an effective Hamiltonian specified in the triangular lattice with possible $p_x\pm i{p}_y$- or $d_{x^2-y^2}\pm i{d}_{xy}$-wave pairing, which has close relevance to the newly…
