Abstract Effects of nonlinearity in the classical field theory for non-integrable systems are
considered, such as soliton scattering, soliton bound states, the fractal nature of resonant …

In the third edition the presentation of new topics has been deliberately kept simple for
pedagogical purposes. Chapter 1 was completed by references to the tidal bore and …

Theoretical physics deals with physical models. The main requirements for a good physical
model are simplicity and universality. Universal models which can be applied to describe a …

We present new numerical and theoretical results concerning kink-antikink collisions in the
classical (nonintegrable) φ 4 field model in one-dimensional space. Earlier numerical …

Solitary, persistent wave packets called solitons hold potential to transfer information and
energy across a wide range of spatial and temporal scales in physical, chemical, and …

For this new journal dealing with nonlinear phenomena we review the setting of several
important current problems in the physics of condensed matter (solids, liquids). We show …

The statistical mechanics of one-dimensional scalar fields governed by nonlinear wave
equations having solitary-wave (soliton) solutions are discussed in detail. Previously …

Much progress has been achieved during the last two decades in the theoretical
understanding of dynamical properties of solids, especially of disordered and anharmonic …

Large local energy fluctuations in liquid water and their physical origin are investigated by
using classical molecular dynamics (MD) calculation and quenching techniques. Performing …

It has recently been shown by NMR techniques that in the high-temperature cubic phase of
BaTiO 3 the Ti ions are not confined to the high-symmetry cubic sites, but rather occupy one …
