Liquids with gas bubbles are commonly seen in medical science, natural science, daily life and engineering. Nonlinear-wave symbolic computation on the (3[Formula: see text]+[Formula: see text]1)-dimensional variable-coefficient Kudryashov–Sinelshchikov model for a bubbly liquid is hereby performed. An auto-Bäcklund transformation and some solitonic solutions are obtained. With respect to the density fluctuation of the bubble-liquid mixture, both the auto-Bäcklund transformation and solitonic solutions depend on the bubble-liquid-viscosity, transverse-perturbation, bubble-liquid-nonlinearity and bubble-liquid-dispersion coefficient functions. We note that some shock waves given by our solutions have been observed by the gas-bubble/liquid-mixture experiments. Effects on a bubbly liquid with respect to the bubble-liquid-viscosity, transverse-perturbation, bubble-liquid-nonlinearity and bubble-liquid-dispersion coefficient functions might be detected by the future gas-bubble/liquid-mixture experiments.

Exhaustive Study

A Yukawa coupling of fermions to the string forming Higgs field leads to the existence of massless1 and massive2,3 fermionic bound states in the vortex that can drastically modify the string dynamics3,4. An exhaustive study of these states is performed. In particular, it is shown that there exists transitions between subsonic and supersonic regimes (i.e. regimes in which the transverse perturbation propagation velocity is less or greater than the longitudinal, sound-like one, respectively), which appear as soon as the massless and massive modes are respectively filled5. This results in modifying the classical stability of cosmic string loops. On the other hand, this confinement mechanism can also be transposed to the the brane context as a viable way for localizing fermions on the brane6.
