Absence of time-reversal symmetry breaking in association with the order parameter of Cooper pair in high $T_c$ superconductivity

Sung-Sik Lee, Ki-Seok Kim, Jae-Hyun Eom +1

As an extension of our previous work on the holon pairing instability in the t-J Hamiltonian [Phys. Rev. B {\bf 66}, 054427 (2002)], we examine the orbital symmetries of holon pair…
