Coexisting Order in the Pseudogap State of Cuprates | | P. Bhattacharyya

11 Jan 2007 | | Subject: | Strongly Correlated Electrons; Disordered Systems and Neural
Networks | | Abstract: | A pseudogap is shown to be a magnetic diffuson (MD) in a state with classical localization order coexisting with Quantum Peierls (QP) order. A soft quantum localization mode, a phason, ensures scale invariance with strong correlations among different momentum states seen as a circular Fermi surface with a gap in ARPES when phase fluctuations are random. These correlations imply a state with coexisting order parameters at distinct length scales. Charge quantization and scale invariance accounts for the sharp peak in the excess tunneling current at V=0. | | Source: | arXiv, cond-mat/0701230 | | Services: | Forum | Review | PDF | Favorites | |
