* ABSTRACT | |||||||
By bosonizing the electronic t-J model exactly on any two-dimensional (2D) lattices, and integrating out the gauge fluctuations combined to slave particles beyond mean fields, we get a theory in terms of U(1) gauge-invariant electron pair and spin condensates. In the sense of mutual Berry phase they turns out to be dual to each other. The mutual-duality is argued to provide natural explanations to essential aspects of high-Tc phenomenology. |
