Connections between kinks with different asymptotics
Vakhid A. Gani, Aliakbar Moradi Marjaneh
In this letter, we show how to build bridges between field-theoretic models that have kink solutions with different asymptotic behavior. We study transformational properties of kin…
Kink dynamics in a high-order field model
Aliakbar Moradi Marjaneh, Vakhid A. Gani, Azam Ghaani +3
We study various properties of topological solitons (kinks) of a field-theoretic model with a polynomial potential of the twelfth degree. This model is remarkable in that it has se…
Equilibration of sinusoidal modulation of temperature in linear and nonlinear chains
Elena A. Korznikova, Vitaly A. Kuzkin, Anton M. Krivtsov +4
The equilibration of sinusoidally modulated distribution of the kinetic temperature is analyzed in the -Fermi-Pasta-Ulam-Tsingou chain with different degrees of nonlinearity and…
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…
