Structure of Magnetic Inhomogeneities in Films with Topological Features
Eugene Magadeev, Robert Vakhitov
This paper considers magnetic films with uniaxial anisotropy of the type "easy plane". It was found that in the presence of structural defects in such films, which are artificially…
Dark discrete breather modes in monoaxial chiral helimagnet with easy-plane anisotropy
I. G. Bostrem, E. G. Ekomasov, J. Kishine +2
Nonlinearity and discreteness are two pivotal factors for an emergence of discrete breather excitations in various media. We argue that these requirements are met in the forced fer…
Integrable Abel equation and asymptotics of symmetry solutions of Korteweg-de Vries equation
B. I. Suleimanov, A. M. Shavlukov
We provide a general solution for a first order ordinary differential equation with a rational right-hand side, which arises in constructing asymptotics for large time of simultane…
Rotobreathers in a chain of coupled elastic rotators
Alexander V. Savin, Ilsiya R. Sunagatova, Sergey V. Dmitriev
Rotobreathers in the chain of coupled linearly elastic rotators are analyzed. Each rotator is a particle connected by a massless elastic rod with a frictionless pivot; it has two d…
Arnold's potentials and quantum catastrophes II
Miloslav Znojil, Denis I. Borisov
The well known phenomenon of avoided level crossing (ALC) can be perceived as a quantum analogue of the Thom's catastrophes in classical dynamical systems. One-dimensional Schrödin…
