24 Aug 2004 | | Journal: | Phys. Rev. B 71, 184514 (2005) | | Subject: | Strongly Correlated Electrons; Superconductivity | cond-mat.str-el cond-mat.supr-con | | Abstract: | We study charge ordered d-wave resonating valence bond states (dRVB) in the doped cuprates, and estimate the energies of these states in a generalized $t-J $ model by using a renormalized mean field theory. The long range Coulomb potential tends to modulate the charge density in favor of the charge ordered RVB state. The possible relevance to the recently observed $4 imes 4$ checkerboard patterns in tunnelling conductance in high $T_c$ cuprates is discussed. | | Source: | arXiv, cond-mat/0408504 | | Services: | Forum | Review | PDF | Favorites | |
