This review reports on the research done during past years on violations of the fluctuation–
dissipation theorem (FDT) in glassy systems. It is focused on the existence of a quasi …

The use of fractal concepts in understanding various growth phenomena, such as molecular
beam epitaxy (MBE) or fluid flow in porous media, is increasingly important these days. This …

A review is given on the theory of vortex-glass phases in impure type-II superconductors in
an external field. We begin with a brief discussion of the effects of thermal fluctuations on the …

Hysteresis loops are often seen in experiments at first-order phase transformations, when
the system goes out of equilibrium. They may have a macroscopic jump (roughly as in the …

Abstract Preface; 1. Introduction; Part I. Spin-Glass Systems: 2. Physics of the spin glass
state; 2. The mean-field theory of spin glasses; 4. Physics of replica symmetry breaking; 5 …

A detailed low-temperature treatment of the domain wall or interface pinning by
imperfections in disordered systems with discrete symmetry of the order parameter is …

Thermodynamic studies of the liquid-vapor transition of He 4 confined in silica aerogel with a
porosity of 95% is reported. In spite of the random nature of the pores, sharp heat-capacity …

The dynamics of a driven interface in a medium with random pinning forces is analyzed. The
interface undergoes a depinning transition where the order parameter is the interface …

We summarize the different puzzles raised by aging experiments of spin glasses and their
various interpretations. We try to reconcile the “real space,” dropletlike pictures with the …

The three-state Potts model with nearest ferromagnetic interaction J on the simple cubic
lattice, exposed to a field which randomly favours one of the states, is studied by finite size …
