With the high-temperature superconductors a qualitatively new regime in the
phenomenology of type-II superconductivity can be accessed. The key elements governing …

This review summarizes recent developments in the theory of spin glasses, as well as
pertinent experimental data. The most characteristic properties of spin glass systems are …

About sixty years ago, the anomalous magnetic response of certain magnetic alloys drew
the attention of theoretical physicists. It soon became clear that understanding these …

We analyze the effect of quenched disorder on spin-1/2 quantum magnets in which
magnetic frustration promotes the formation of local singlets. Our results include a theory for …

The transverse field Ising and XY models (the simplest quantum spin models) provide the
organising principle for the rich variety of interconnected subjects which are covered in this …

The phase of condensed matter known as spin glasses has become a vital and productive
area of research. Historically, experiment has suggested unusual effects which have brought …

The recent success in quantum annealing, ie, optimization of the cost or energy functions of
complex systems utilizing quantum fluctuations is reviewed here. The concept is introduced …

A phenomenological theory of the ordered phase of short-range Ising spin glasses is
developed in terms of droplet excitations and presented in detail. These excitations have …

We carefully examine common measures of dynamical heterogeneity for a model polymer
melt and test how these scales compare with those hypothesized by the Adam and Gibbs …

The different physical aspects of glass transitions are reviewed and models aiming at their
explanation are described. The following three main aspects are distinguished: the degree …
