Charge dynamics in the phase string model for high-Tc superconductors
Zheng-Cheng Gu, Zheng-Yu Weng
An understanding of the anomalous charge dynamics in the high-Tc cuprates is obtained based on a model study of doped Mott insulators. The high-temperature optical conductivity is…

Upper Pseudogap Phase: Magnetic Characterizations
Zheng-Cheng Gu, Zheng-Yu Weng
It is proposed that the upper pseudogap phase (UPP) observed in the high-Tc cuprates correspond to the formation of spin singlet pairing under the bosonic resonating-valence-bond (…

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…
