Optomechanical Akhmediev Breathers
Laser & Photonics Reviews, 2018 AbstractThe Akhmediev breather has attracted considerable attention over the past decades in various fields such as hydrodynamics, plasma physics, and nonlinear optics because of its wide applications and its importance in understanding nonlinear coherent phenomena.

Breather dynamics in ultrafast fibre lasers and their intelligent control [PDF]
, 2023 We review our recent work on the dynamics of breathing solitons in fibre lasers, including single breathers, breather molecular complexes, breather explosions and breather frequency locking at Farey fractions, and their control by genetic ...

Dissipative optical breather molecular complexes [PDF]
, 2020 We demonstrate different types of breathing soliton complexes in a mode-locked fibre laser: multi-breather molecules, and molecular complexes arising from the binding of two breather-pair molecules or a breather-pair molecule and a single ...

Breather Molecular Complexes in a Passively Mode‐Locked Fiber Laser [PDF]
, 2021 Breathing solitons are nonlinear waves in which the energy concentrates in a localized and oscillatory fashion. Similarly to stationary solitons, breathers in dissipative systems can form stable bound states displaying molecule-like dynamics, which are ...

Self-optimising breather ultrafast fibre laser [PDF]
, 2021 We demonstrate the self-optimisation of the breather regime in an ultrafast fibre laser through an evolutionary algorithm. Depending on the specified merit function, single breathers with controllable breathing ratio and period, and breather molecular ...

Two-dimensional mobile breather scattering in a hexagonal crystal lattice [PDF]
, 2021 We describe the full two-dimensional scattering of long-lived breathers in a model hexagonal lattice of atoms. The chosen system, representing an idealized model of mica, combines a Lennard-Jones interatomic potential with an "egg-box"harmonic potential ...

Weekends-off efavirenz-based antiretroviral therapy in HIV-infected children, adolescents, and young adults (BREATHER): a randomised, open-label, non-inferiority, phase 2/3 trial. [PDF]
, 2016 BACKGROUND: For HIV-1-infected young people facing lifelong antiretroviral therapy (ART), short cycle therapy with long-acting drugs offers potential for drug-free weekends, less toxicity, and better quality-of-life.

Bounded States for Breathers–Soliton and Breathers of Sine–Gordon Equation [PDF]
Nonlinear Dynamics, 2021 Abstract The Wronskians solutions to the sine-Gordon (sG) equation that can provide interaction of different kinds of solutions are revisited. A novel expression N-soliton solution with a nonzero background is presented which is used to construct the soliton and breather solutions.

The Akhmediev breather is unstable [PDF]
São Paulo Journal of Mathematical Sciences, 2019 In this note, we give a rigorous proof that the NLS periodic Akhmediev breather is unstable. The proof follows the ideas in [17], in the sense that a suitable modification of the Stokes wave is the global attractor of the local Akhmediev dynamics for sufficiently large time, and therefore the latter cannot be stable in any suitable finite energy ...
