摘要：

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