A unified theoretical treatment of single-particle, e.g., density of states, and two-particle, e.g., transport properties of substitutionally disordered alloys, is presented using the embedded-cluster method (ECM) within the coherent-potential approximation. Comparison with results of exact numerical simulations of the ac conductivity shows that the ECM allows for the proper inclusion of vertex corrections and provides a reliable and accurate technique for determining the transport properties of alloys.
