Modulation instability and wavenumber bandgap breathers in a time layered phononic lattice
Physical Review ResearchWe provide the first experimental realization of wavenumber bandgap (q-gap) breathers. Experiments are obtained in the setting of a time-periodic phononic lattice where the model and experiment exhibit good qualitative agreement.

Analytical technique and diverse chaos-identifying tools for the time fractional symmetric regularized long wave equation [PDF]
Scientific ReportsThe nonlinear conformable time-fractional symmetric regularized long wave (SRLW) equation is important in physics because it captures memory effects in fluid flow and describes how weakly nonlinear pulses evolve in optical fibers.

Mouth breathing reduces oral function in adolescence [PDF]
Scientific ReportsAlthough humans breathe naturally through the nostrils, mouth breathing in children has recently gathered attention. In this study, we hypothesized that tongue function and its related maxillofacial morphology would affect breathing in adolescence.

Spatio-temporal breather dynamics in microcomb soliton crystals [PDF]
Light: Science & ApplicationsSolitons, the distinct balance between nonlinearity and dispersion, provide a route toward ultrafast electromagnetic pulse shaping, high-harmonic generation, real-time image processing, and RF photonic communications. Here we uniquely explore and observe

Vector breathers in the Manakov system [PDF]
Studies in Applied Mathematics, 2023 We study theoretically the nonlinear interactions of vector breathers propagating on an unstable wavefield background. As a model, we use the two-component extension of the one-dimensional focusing nonlinear Schrödinger equation—the Manakov system.

Stability of Breathers for a Periodic Klein–Gordon Equation [PDF]
EntropyThe existence of breather-type solutions, i.e., solutions that are periodic in time and exponentially localized in space, is a very unusual feature for continuum, nonlinear wave-type equations.
