It enables us to study clustering,
segrigation, short- range ordering and local lattice distortions due to
size mismatch. Coupled with the cluster-variation technique and the orbital
peeling method of Burke, we can study the phase stability and phase diagram
of binary and ternary alloy systems. An extension of the method allows
us to study systems with potentials which vary randomly with time.
A recent interest is the extension
of the method to deal with response functions and generalized susceptibilities
in random systems.
The group is also interested in rough
surfaces, catalysis and electronic and magnetic properties of finite clusters.
