Kinetic energy driven superconductivity in the electron doped cobaltate Na${}_x$CoO${}_2\cdot y$H${}_2$O

Bin Liu, Ying Liang, Shiping Feng +1

Within the charge-spin separation fermion-spin theory, we have shown that the mechanism of superconductivity in the electron doped cobaltate Na${}_x$CoO${}_2\cdot y$H${}_2$O is asc…
