Universal scaling behavior of the c-axis resistivity of high-temperature superconductors
Y. H. Su, H. G. Luo, T. Xiang
We propose and show that the c-axis transport in high-temperature superconductors is controlled by the pseudogap energy and the c-axis resistivity satisfies a universal scaling law…
Spin dynamics in a doped-Mott-insulator superconductor
W. Q. Chen, Z. Y. Weng
We present a systematic study of spin dynamics in a superconducting ground state, which itself is a doped-Mott-insulator and can correctly reduce to an antiferromagnetic (AF) state…
Effect of impurity states on the NMR spectra of high- cuprates
J. Chang, Y. H. Su, H. G. Luo +2
A strong nonmagnetic impurity can induce a resonance state in the d-wave superconducting state. As far as magnetic properties are concerned, this resonance state behaves effectivel…
Pseudogap Phase: Exchange Energy Driven vs. Kinetic Energy Driven
Zhengcheng Gu, Tao Li, Zheng-Yu Weng
We show that both kinetic and superexchange energies of the t-J model may be read off from the optical data, based on an optical sum rule for the Hubbard model. Then we comparative…
Inhomogeneity in doped Mott insulator
Dung-Hai Lee
We introduce the concept that there are two generic classes of Mott insulators in nature. They are distinguished by their responses to weak doping. Doped charges form cluster (i.e.…
