Zhao | | Subject: | Superconductivity; Strongly Correlated Electrons | cond-mat.supr-con cond-mat.str-el | | Abstract: | Within the charge-spin separation fermion-spin theory, the mechanism of superconductivity in Na$_{x}$CoO$_{2}cdot y$H$_{2}$O is studied. It is shown that dressed fermions interact occurring directly through the kinetic energy by exchanging magnetic excitations. This interaction leads to a net attractive force between dressed fermions(then the electron Cooper pairs), and their condensation reveals the superconducting ground state. The optimal superconducting transition temperature occurs in the electron doping concentration $deltaapprox 0.29$, and then decreases for both underdoped and overdoped regimes, in qualitative agreement with the experimental results. | | Source: | arXiv, cond-mat/0505228 | | Services: | Forum | Review | PDF | Favorites | |
