  • Description
  • Programme

Soliton-assisted transport (with commercial purposes) was (re)invented in modern times by the ship-building architect and engineer J. S. Russell who in mid-XIXth Century made the discovery of the solitary wave at Union Canal near Edinburgh. Indeed, solitary waves, e.g., at the sea shore, and bores in rivers, permit matter transport and surfing. Bores had been observed and used by peasants in China several centuries ago. They used them to transport goods surfing upstream, with small boats, and getting back to origin with the downstream river flow. In the last quarter of the XIXth century, such waves received a good theoretical explanation by Boussinesq (B) and Lord Rayleigh. Later on came Korteweg and de Vries (KdV) who rediscovered the solitary wave evolution equation (fifteen years after Boussinesq). It was not until mid-XXth Century that the curiosity of the solitary wave attracted the interest of N. J. Zabusky and M. D. Kruskal who numerically explored the solutions of the BKdV theory, and their (overtaking) collisions, and coined the soliton word and concept. Their research was motivated by earlier work done by Fermi, Pasta and Ulam (FPU) on heat transfer and equipartition in (anharmonic) lattices at Los Alamos National Lab using the MANIAC computer. Eventually, subsequent mathematical work about BKdV theory and other soliton-bearing dynamics led to a new area in Applied Mathematics and General Physics (in particular, by using computers to gain insight and not just numerical results).

In the last fifteen years, the soliton concept has been applied to such complex phenomena as the coupled motion of nuclei and electrons in crystalline solids (insulators and semiconductors, in particular). This constitutes an interesting problem because while the heavy "particles" are treated classically, the lighter ones (electrons or positive holes) must be treated quantum mechanically. Theory has shown the possibility of transferring the soliton-like motion to the charges which could "surf" on the soliton wave. This opens the path to practical application in nano-electronics through the design of novel, ultrafast transistors with extremely low heat dissipation.

At present, the soliton concept and other related concepts like discrete breathers (a.k.a. intrinsic localized modes genuine of perfect crystal lattices) underlie a powerful paradigm providing a unifying understanding of a disparate collection of phenomena found in several branches of Science and not just Physics (Fluid Physics, Hydraulics, Oceanography, Nonlinear Optics and Lasers, Optical Fiber transmission, Acoustics, Plasmas, Science and Engineering of advanced materials, Nano-electronics, Cosmological relativity, Neuro-dynamics, Robotics, etc.).
