Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest ...

Wave motion lies at the heart of many disciplines in the physical sciences and engineering. For example, problems and applications involving light, sound, heat or fluid flow are all likely to involve ...

Journal of Nonlinear Waves is the home for the field of nonlinear wave phenomena, broadly defined. It publishes authoritative articles on theoretical and computational aspects of nonlinear waves ...

Under investigation in this paper is a (2+1)-dimensional nonlinear Schrödinger equation (NLS), which is a generalisation of the NLS equation. By virtue of Wronskian determinants, an effective method ...

Deep-water wave groups are known to be unstable and become rogue. Such unstable wave groups propagate independently regardless of interference. Results seem to support the concept of an unperturbed ...

The Kawahara equation is an asymptotic model of weakly nonlinear wave phenomena when third and fifth order dispersion are in balance. The model equation consists of the Korteweg-de Vries equation with ...

Nonlinear waves in physical systems are wave phenomena governed by equations in which the restoring forces or constitutive relations depend nonlinearly on the field amplitudes, leading to ...

Tiny waves, big implications: Electron microscope image of the superfluid wave tank used in the experiments (blue) coupled to an optical fibre which brings laser light in and out of the device. The ...

Soon to be ringing: artist’s impression of two black holes that are about to merge. (Courtesy: NASA) Two independent teams have shown that gravitational waves emanating from the distorted remnants of ...
