“…Solitons (or solitary waves) are present in a wide range of physics such as optics [1,2], superconducting Josephson junction arrays [3,4,5], particle and nuclear physics [6,7], condensed matter physics [8,9,10,11,12,13,14,15], and many others [16,17,18,19]. They are robust with respect to small perturbations, they can travel long distances maintaining their shape, and survive collisions with each other.…”
