Direct Calculation of Breather S Matrices [PDF]
, 1999 We formulate a systematic Bethe-Ansatz approach for computing bound-state (``breather'') S matrices for integrable quantum spin chains. We use this approach to calculate the breather boundary S matrix for the open XXZ spin chain with diagonal boundary ...

Breather Wave and Traveling Wave Solutions for A (2 + 1)-Dimensional KdV4 Equation
Advances in Mathematical Physics, 2022 In this paper, an integrable (2 + 1)-dimensional KdV4 equation is considered. By considering variable transformation and Bell polynomials, an effective and straightforward way is presented to derive its bilinear form.

Interaction solution to the (3+1)-D negative-order KdV first structure
Partial Differential Equations in Applied Mathematics, 2023 We derive N-solitons and interaction solution for the (3+1)-D negative-order KdV first structure that arises in shallow-water waves. We use the bilinear scheme and the simplified Hirota technique for this solution. From the multiple solitons solution, we

Spectral theory of soliton and breather gases for the focusing nonlinear Schrödinger equation [PDF]
, 2020 Solitons and breathers are localized solutions of integrable systems that can be viewed as “particles” of complex statistical objects called soliton and breather gases.

Discrete Nonlinear Schr{\"o}dinger Breathers in a Phonon Bath
, 1999 We study the dynamics of the discrete nonlinear Schr{\"o}dinger lattice initialized such that a very long transitory period of time in which standard Boltzmann statistics is insufficient is reached.
