What does Soliton mean? - definitions

WebThe neutral soliton has one electron in the mid-gap state and the positively and negatively charged solitons have zero or two electrons respectively in the mid-gap state. Consequently, the spin-charge relations of solitons are reversed; charged solitons are non-magnetic, whereas a neutral soliton has spin 2. The reversed spin-charge ...

Soliton - Wikipedia

WebSep 20, 1976 · The charged soliton solutions are periodic functions of the time, and a first approximation to the quantum theory can be obtained from the Bohr-Sommerfeld quantization rule. This rule is shown to be equivalent to requiring the charge to be quantized in integer values [8] . A more profound discussion of the quantum theory requires the use … In mathematics and physics, a soliton or solitary wave is a self-reinforcing wave packet that maintains its shape while it propagates at a constant velocity. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. (Dispersive effects are a property of certain systems where the … See more A single, consensus definition of a soliton is difficult to find.
