Research Abstract

The aim of this research project is to reveal the nature of the pseudo-gap (PG)state in high-Tc cuprates by studying the local structure of hidden order-parameters around vortex cores and stripe states. We find that a stripe-like modulating d-wave RVB state can be a meta-stable state in the bulk systems, and a plausible candidate of the PG state.
