Talk:Soliton

message: from the following it would be useful to know over what distance this was achieved, as otherwise its meaningless:
In 1998, Thierry Georges and his team at France Telecom R&D Center, combining optical solitons of different wavelengths (wavelength division multiplexing), demonstrated a data transmission of 1 terabit per second (1,000,000,000,000 units of information per second).

message: The inverse scattering transform technique is universally regarded as a landmark in the theory of partial differential equations and applied mathematics in general, so I think it amply deserves its own article, which this article should cite.  The proposed article on inverse scattering should probably also mention applications to exact solutions of Einstein's field equations as well as to solving the Korteweg-de Vries equation and sine-Gordon equation.
I think this article should also mention the closely related concept of a completely integrable system, and the observation of Shiing-Shen Chern that these can be formulated in terms of appropriate flat (zero curvature) connections.

P.S. Hi, MarSch, I just noticed you seem to have a link to a web page owned by someone I know at the top of your user page!

:Yeah, I came across it and I thought that was a good place to store it. I don't know that person though. --MarSch 14:56, 24 Jun 2005 (UTC)

message: Could someone please add some text explaining the relationship between a Soliton and a Standing Wave? They seem to be intimately related. See how both are discussed in the article on Modelocking. For example, is it accurate to describe a Soliton as a "Travelling" Standing Wave? Or a Standing Wave as a Stationary Soliton? --Nick 17:44, 6 July 2006 (UTC)

message: The article states that solitons belong to a class of phenomomena known as "topological defects". I'm not sure that this is true for all solitons. I think that there may be some solitons (such as the soliton solution to the nonlinear Schrodinger equation) that cannot be described as topological solitons - although I am not certain of this. Does anyone know if this is the case?

replies: text: See Q-balls. There instead of a conserved topological charge, there is a different kind of charge Q (for instance, a Noether charge associated with U(1) symmetry) that prevents the disturbance from dissipating. Steve Avery (talk) 00:38, 14 January 2008 (UTC)
thread_title:  Topological defects vs. solitons 

message: This paragraph does not well-serve Wikipedia's function of teaching.
The above impressive experiments have not translated to actual commercial soliton system deployments however, in either terrestrial or submarine systems, chiefly due to the Gordon-Haus (GH) jitter.     The Gordon-Haus jitter is jitter in what? Phase? Name a parameter, give a link  The GH jitter requires sophisticated, expensive compensatory solutions that ultimately makes DWDM soliton transmission in the field unattractive, compared to the conventional non-return-to-zero/return-to-zero paradigm.  Say: compared to conventional long-haul methods. Period. It is nice that you know modulation and coding techniques, nice you may follow their evolution in the years ahead, but how we do data-layer modulation is not the first thing to bring up in an exposition of PHY layer propagation issues.  Further, the likely future adoption of the more spectrally efficient phase-shift-keyed/QAM formats makes soliton transmission even less viable, due to the Gordon-Mollenauer effect. Consequently, the long-haul fiberoptic transmission soliton has remained a laboratory curiosity   It would be helpful to say what the Gordon-Mollenauer effect is and to provide a reference, or simply remove it.  A broader conclusion would be more correct and more helpful:  Improvements in both the transport and amplification of light pulses and in the encoding of the information carried by them have blocked solitons from commercial acceptance.
We are here to help others.  You can do this better than I can, so just do it.  Thanks.

thread_title: More suggestions - weak paragraph

message: Research published in the August 30 2010 of Physical Review theorizes a new form of oscillator using solitons. "You might use this effect to create an oscillator the uses much less energy than those in use today. And the military could use them in secure communications as well. In theory you could change the frequency of these devices quite rapidly, making the signals very hard for enemies to intercept or jam" This has great potential implications on existing RF communications. The predicted oscillator would be much more stable than traditional oscillators along with wide variations in current applied to the oscillator which would greatly reduce unwanted noise in the system . for stable

I scanned through the book by John Scott Russel
Nice read..
He speaks in layman terms and not in scientific formulas..It's easy to follow.
I couldn't find the section on "Rogue Waves" or "Tidal Waves"
What page is it on???
I used to live in Ohio , On lake Erie..
Lake Erie is a flat "slate bottom" lake , only 20 foot deep.. There are some holes that go down to 50 to 120 feet deep , but mostly it 20 foot deep..
During the "Gales of November" you can get 32 foots waves.. 12 foot higher than the lake is deep...
So in an aquarium 1 inch deep , you should be able to get waves 1.5 to 2 or more inches high.. (rogue waves)
What would be the frequency and or pressure needed to create those "Rogue Waves" ??
Figure out how to create a rogue wave in water and solids and gasses are only a step away.. ( harder or softer )
I think Tesla's "Earth Quake Machine" was a rogue wave generator. I think it worked at low frequencies..

message: Could you include a section that explains how these naturally form, and why they are relevant to some of article references - eg the tidal bores and in fibre-optics? And how does a solitaon disipate - how does it disappear? 122.57.59.99 (talk) 08:41, 22 April 2023 (UTC)
thread_title:  How Solitons form naturally 

message: In Manicure's paper solitons are described as "ubiquitous in nature", which means something that is found everywhere or seemingly present in all places at the same time, in this case, within the context of nature. It suggests something that is both widespread and common, often playing an essential role in the natural world.
I have not been able to find this to be true. Are they the figment of the mathematicians imagination? 
Where do they exist in nature?
(Manukure has not responded to my request for supporting evidence)
