Collision of kinks free of the Peierls-Nabarro barrier in the regime of strong discreteness
Alidad Askari, Aliakbar Moradi Marjaneh, Zhanna G. Rakhmatullina +5
The two major effects observed in collisions of the continuum kinks are (i) the existence of critical collision velocity above which the kinks always emerge from the collisio…
Effect of discrete breathers on macroscopic properties of the Fermi-Pasta-Ulam chain
Elena A. Korznikova, Alina Y. Morkina, Mohit Singh +5
The effect of discrete breathers (DBs) on macroscopic properties of the Fermi-Pasta-Ulam chain with symmetric and asymmetric potentials is investigated. The total to kinetic energy…
Effect of discrete breathers on the specific heat of a nonlinear chain
Mohit Singh, Alina Y. Morkina, Elena A. Korznikova +6
A nonlinear chain with six-order polynomial on-site potential is used to analyze the evolution of the total to kinetic energy ratio during development of modulational instability o…
Superheavy objects composed of nuclear and dark matter
Vakhid A. Gani, Maxim Yu. Khlopov, Dmitry N. Voskresensky
We consider a model of He atomic dark matter formed by Coulomb binding of the hypothetical stable double-charged massive particles with nuclei of primordial helium. Suc…
Multi-kink scattering in the double sine-Gordon model
Vakhid A. Gani, Aliakbar Moradi Marjaneh, Danial Saadatmand
We study collisions of two, three, and four kinks of the double sine-Gordon model. The initial conditions are taken in a special form in order to provide collision of all kinks in…
