On the analogy between consequences of the breather model of particles interaction and anomalous flow of Helium-II
R. K. Salimov, E. G. Ekomasov
The article deals with the sin-Gordon model and considers the interaction of breathers localized on moving impurities. Numerical simulation of collective behavior of such objects r…

Dynamics of the multi-soliton waves in the sine-Gordon model with two identical point impurities
Azamat M Gumerov, Roman V Kudryavtsev, Evgenii G Ekomasov
The particular type of four-kink multi-solitons (or quadrons) adiabatic dynamics of the sine-Gordon equation in a model with two identical point attracting impurities has been stud…
