Superfluid weight vs. superconducting temperature based on a U(1) slave-boson approach to the t-J Hamiltonian

Sung-Sik Lee, Sung-Ho Suck Salk

Based on an improved U(1) slave-boson approach to the t-J Hamiltonian, we invest igate a relationship between the superfluid weight $n_{s} / m^{*}$ (the superconducting charge carrier den…

Importance of Coupling between the Charge and Spin Degrees of Freedom in High Tc Superconductivity

Sung-Sik Lee, Sung-Ho Suck Salk

Based on an improved SU(2) slave-boson approach showing coupling between the cha rge and spin degrees of freedom, we derive a phase diagram of high $T_{c}$ cuprate s which displays b…

Origin of the Quasiparticle Peaks of Spectral Functions in High $T_{c}$ Cuprates

Sung-Sik Lee, Sung-Ho Suck Salk

Based on the SU(2) slave-boson approach to the t-J Hamiltonian, we examine the cause of the sharp peaks('quasiparticle' peaks) in the observed spectral functions in high $T_{c}$ cupr…
