Zabusky and Kruskal: solitons and recurrence in a collisionless plasma

Contribution grade

Fluids and plasma · EMPIRICAL

Reference score200,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Used numerical study of the Korteweg–de Vries equation to exhibit stable interacting solitary waves, introduced the term soliton and connected their interactions to recurrence.

Scientific scope

The record is the exact 1965 Physical Review Letters paper. Earlier solitary-wave observations, the Fermi–Pasta–Ulam report, inverse scattering, later integrable-systems theory and applications remain separate.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1965 Physical Review Letters paper. Earlier solitary-wave observations, the Fermi–Pasta–Ulam report, inverse scattering, later integrable-systems theory and applications remain separate.
