Quantum phase transitions in superconductors
Ki-Seok Kim, Sung-Sik Lee, Jae-Hyeon Eom +1
Based on an effective Lagrangian obtained from the holon-pair boson theory of Lee and Salk [Phys. Rev. B {\bf 64}, 052501 (2001)] for high cuprates, we explore physical state…

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