Scaling behavior in the optical conductivity of the two dimensional systems of strongly correlated electrons based on the U(1) slave-boson approach to the t-J Hamiltonian
Jae-Hyeon Eom, Sung-Sik Lee, Ki-Seok Kim +1
The U(1) holon-pair boson theory of Lee and Salk(Phys. Rev. B 64, 052501 (2001)) is applied to investigate the quantum scaling behavior of optical conductivity in the two dimension…
Superconductivity in the presence of antiferromagnetism for high Tc cuprates
Ki-Seok Kim, Sung-Sik Lee, Jae-Hyeon Eom +1
Using the U(1) holon pair slave boson theory [Phys. Rev. B 64, 052501 2001)], we derive a low energy field theory of dealing with both d-wave superconductivity and antiferromagneti…
Holon-pair boson theory based on the U(1) and SU(2) slave-boson approaches to the t-J Hamiltonian
Sung- Sik Lee, Sung-Ho Suck Salk
To supplement our recent brief report on the theory of holon-pair boson approach to the t-J Hamiltonian [S.-S. Lee and Sung-Ho Suck Salk, Phys. Rev. B {\bf 64}, 052501(2001)], in t…
Doping dependence of bose condensation energy and correlations with spectral peak intensity and superfluid weight in high Tc cuprates
Sung-Sik Lee, Sung-Ho Suck Salk
Based on our recent holon-pair boson theory of the t-J Hamiltonian (Phys. Rev. B 64, 052501 (2001)) we report the doping dependence of the bose condensation energy, superfluid weig…
