Spatial decay of the single-particle density matrix in tight-binding metals: +AFwAXA- analytic results in two dimensions

S. N. Taraskin, P. A. Fry, Xiadong Zhang +2

Analytical results for the asymptotic spatial decay of the density matrix $+AFw-rho(+AFw-bfr,+AFw-bf{r}^{+}AFw-prime)$ in the tight-binding model of the two-dimensional metal are…
