Underlying Pairing States of High T c Superconductivity
並列摘要
In this work, I present a microscopic theory I proposed recently to describe high-Tc superconductivity in cuprates. I show that coherent pairing states consisting of extended singlet Cooper pairs and triplet π pairs can manifest the co-existence of the Mott insulating antiferromagnetic order and the d-wave superconducting order. From this configuration of coherent pairing states, I can describe both the single electron properties and the low energy collective excitations in high Tc superconductivity in the same framework. The quasiparticle can be derived directly with respect to the coherent pairing states. While, the low-lying quantum fluctuations associated with spin-wave and charge excitation can be investigatedfrom the path integral of the coherent pairing states.
