Spinning gravitating Skyrmions in generalized Einstein-Skyrme model
Ilya Perapechka, Yakov Shnir
We investigate properties of self-gravitating isorotating Skyrmions in the generalized Einstein-Skyrme model with higher-derivative terms in the matter field sector. These stationa…

Fractional Hopfions in the Faddeev-Skyrme model with a symmetry breaking potential
A. Samoilenka, Ya. Shnir
We construct new solutions of the Faddeev-Skyrme model with a symmetry breaking potential admitting vacuum. It includes, as a limiting case, the usual symmetry breaki…

Oscillons in the presence of external potential
Tomasz Romańczukiewicz, Yakov Shnir
We discuss similarity between oscillons and oscillational mode in perturbed . For small depths of the perturbing potential it is difficult to distinguish between oscillons and…
