An introductory review of the central ideas in the modern theory of dynamic critical
phenomena is followed by a more detailed account of recent developments in the field. The …

In this paper we summarize the work done by our group in develo** and applying the
closed time-path Green function (C1'PGF) formalism, first suggested by J. Schwinger and …

We present a detailed study of the methods of summation based on Borel transformation
and conformal map**, which we have used to calculate critical exponents of the n-vector …

We present a systematic expansion for studying an infrared-stable fixed point of gauge
theories with massless fermions. These results are combined with information from strong …

The pivot algorithm is a dynamic Monte Carlo algorithm, first invented by Lal, which
generates self-avoiding walks (SAWs) in a canonical (fixed-N) ensemble with free endpoints …

We present a new calculation of the critical exponents of the n-vector model through field-
theoretical methods. The coefficients of the renormalization functions of the (ϕ→ 2) 2 theory …

Abstract The Martin-Siggia-Rose field theories associated with the critical dynamics of mode-
coupling systems, are renormalized in a way which decouples statics from dynamics …

We review theoretical and experimental studies of the AC dielectric response of
inhomogeneous materials, modelled as bond percolation networks, with a binary (conductor …

The long-distance properties of classical Heisenberg ferromagnets below the transition point
are related to a continuous-field theory, the nonlinear σ model. The renormalizability of this …

We develop a systematic approach to the calculations of finite size effects in phase
transitions. The method consists of constructing an effective hamiltonian for the …
