Bound Coherent Structures Propagating on the Free Surface of Deep Water
Fluids, 2021 This article presents a study of bound periodically oscillating coherent structures arising on the free surface of deep water. Such structures resemble the well known bi-soliton solution of the nonlinear Schrödinger equation. The research was carried out

Optics Letters, 2014 The dynamics of two component coupled Airy beams is investigated. In the linear propagation regime a complete analytic solution describes breather like propagation of the two components featuring non-diffracting self-accelerating Airy behavior. The superposition of two beams with different input properties opens the possibility to design more complex ...

Collective influence of impurities on the dynamics of kinks of modified sine-Gordon equation [PDF]
Компьютерные исследования и моделирование, 2013 We investigated numerically the dynamics of kinks of modified sine-Gordon equation in the model with localized spatial modulation of a periodic potential (or impurity). We considered the case of two identical impurities.

Discrete moving breather collisions in a Klein-Gordon chain of oscillators [PDF]
, 2007 We study collision processes of moving breathers with the same frequency, traveling with opposite directions within a Klein-Gordon chain of oscillators. Two types of collisions have been analyzed: symmetric and non-symmetric, head-on collisions.

Breather lattice and its stabilization for the modified Korteweg-de Vries equation [PDF]
, 2003 We obtain an exact solution for the breather lattice solution of the modified Korteweg-de Vries (MKdV) equation. Numerical simulation of the breather lattice demonstrates its instability due to the breather-breather interaction.

Stability of Quantum Breathers [PDF]
Physical Review Letters, 2006 Using two methods we show that a quantized discrete breather in a 1-D lattice is stable. One method uses path integrals and compares correlations for a (linear) local mode with those of the quantum breather. The other takes a local mode as the zeroth order system relative to which numerical, cutoff-insensitive diagonalization of the Hamiltonian is ...
