Small polarons and c-axis transport in highly anisotropic metals

A. F. Ho, A. J. Schofield

Motivated by the anomalous c-axis transport properties of the quasi two-dimensional metal, $\mathrm{S}{\mathrm{r}}_2\mathrm{Ru}{\mathrm{O}}_4$, and related compounds, we have studied the interlayer hopping of singl…
