Abstract
We extend a recently proposed numerical renormalization-group procedur e to efficiently calculate specific heats. Analytically, we show that the extension yields the exact zero-temperature specific heat (C=O) fo r Fermi liquids. Numerically, we compute the temperature-dependent spe cific heat for the Anderson model.
