Query: Recent Results on the Decay of Metastable Phases   We review some aspects of current knowledge regarding the decay of metastable
phases in many-particle systems. In particular we emphasize recent theoretical
and computational developments and numerical results regarding homogeneous
nucleation and growth in kinetic Ising and lattice-gas models. An introductory
discussion of the droplet theory of homogeneous nucleation is followed by a
discussion of Monte Carlo and transfer-matrix methods commonly used for
numerical study of metastable decay, including some new algorithms. Next we
discuss specific classes of systems. These include a brief discussion of recent
progress for fluids, and more exhaustive considerations of ferromagnetic Ising
models ({\it i.e.}, attractive lattice-gas models) with weak long-range
interactions and with short-range interactions. Whereas weak-long-range-force
(WLRF) models have infinitely long-lived metastable phases in the
infinite-range limit, metastable phases in short-range-force (SRF) models
eventually decay, albeit extremely slowly. Recent results on the finite-size
scaling of metastable lifetimes in SRF models are reviewed, and it is pointed
out that such effects may be experimentally observable.
