15 Jan 2006 | Subject: | Strongly Correlated Electrons; Superconductivity | Abstract: | Within the t-J model, the heat transport of electron-doped cobaltates is studied based on the fermion-spin theory. It is shown that the temperature dependent thermal conductivity is characterized by the low temperature peak located at a finite temperature. The thermal conductivity increases monotonously with increasing temperature at low temperatures T $<$ 0.1$J$, and then decreases with increasing temperature for higher temperatures T $>$ 0.1$J$, in qualitative agreement with experimental result observed from Na$_{x}$CoO$_{2}$ . | Source: | arXiv, cond-mat/0601320 | Services: | Forum | Review | PDF | Favorites |
