Soliton water waves can travel several kilometers without any significant change in their shape or amplitude, as opposed to normal waves, which widen as they travel, and eventually disappear. Discovered over 150 years ago in water canals, solitons represent a surprising phenomenon of wave propagation and have been observed in natural phenomena including moving sand dunes and space plasmas. A unique aspect of solitons is that they can retain their shape because of non-linear and dispersive...

Development of electronics and communication requires a hardware base capable for increasingly larger precision, ergonomics and throughput. For communication and GPS-navigation satellites, it is of great importance to reduce the payload mass as well as to ensure the signal stability. Last year, researchers from the Moscow State University (MSU) together with their Swiss colleagues from EFPL performed a study that can induce certain improvements in this direction. The scientists demonstrated...

A Chinese team has performed simulations to help understand the occurrence of multiple solitary optical waves that are used to reconfigure optical beams Researchers have designed the first theoretical model that describes the occurrence of multiple solitary optical waves, referred to as dark photovoltaic spatial solitons. The findings by Yuhong Zhang, a physicist from the Xi´an Institute of Optics and Precision Mechanics of the Chinese Academy of Science, and his colleagues is about...

A coupled line of swinging pendulums apparently has nothing in common with an elastic film that buckles and folds under compression while floating on a liquid, but scientists at the University of Chicago and Tel Aviv University have discovered a deep connection between the two phenomena. Energy carried in ordinary waves, like those seen on the ocean near a beach, quickly disperses. But the energy in the coupled pendulums and in compressed elastic film concentrates into different kinds of...

Researchers at the National Institute of Standards and Technology (NIST) have found theoretical evidence* of a new way to generate the high-frequency waves used in modern communication devices such as cell phones. Their analysis, if supported by experimental evidence, could contribute to a new generation of wireless technology that would be more secure and resistant to interference than conventional devices. The team's findings point toward an oscillator that would harness the spin of...

NIST physicists predict new form of soliton in ultracold gases Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but theoreticians at the Joint Quantum Institute (JQI) , a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, and their colleagues in India and the George Mason University, now believe that there may be a new...

Swooping through space are solitary waves, which in theory do not change form or lose energy as they go along. These waves, which exist on Earth in different media, have been detected and explained for the first time in space thanks to Cluster data. In theory, these solitary waves, called solitons, propagate endlessly maintaining their shape and form as well as velocity, which means that they do not lose energy with time. The phenomenon was first noticed in a water canal in England in 1834...
