摘要：
We present results for the Kondo lattice model of strongly correlated electrons, in one, two, and three dimensions, obtained from high-order linked-cluster series expansions. Results are given for various ground-state properties at half filling, and for spin and charge excitations. Estimates for the location of the quantum critical point in the square and simple cubic lattices are made.
