moore has published many papers in statistical physics covering a wide range of topics. his early research was on the application of scaling theories to magnetic spin systems and superfluidity, and contained a series of useful results on critical indices. he then applied renormalisation group ideas to polymer solutions and clarified the relationship of this approach to previous theories; a particularly interesting result concerned the retrieval of the flory index under approximation schemes. after some work on critical behaviour on surfaces, he joined the (then) new spin glass field, and in collaboration with alan bray wrote a series of important papers both on replica symmetry breaking in these systems and on their properties as revealed by computer simulation. in particular, he is associated with the droplet scaling theory of the spin glass state. in recent years, michael has extended this work to structural glasses.
