Phonons scattering off discrete asymmetric solitons in the absence of a Peierls-Nabarro potential
Danial Saadatmand, Aliakbar Moradi Marjaneh, Alidad Askari +1
We analyze the interaction of lattice vibrations (phonon wave-packets) with an asymmetric kink soliton initially at rest. We employ the model in one space and one time dimens…
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…
A new look at the double sine-Gordon kink-antikink scattering
Ekaterina Belendryasova, Vakhid A. Gani, Aliakbar Moradi Marjaneh +2
We study the kink-antikink scattering within the double sine-Gordon model. In the numerical simulations we found a critical value of the initial velocity , which s…
Scattering of the double sine-Gordon kinks
Vakhid A. Gani, Aliakbar Moradi Marjaneh, Alidad Askari +2
We study the scattering of kink and antikink of the double sine-Gordon model. There is a critical value of the initial velocity of the colliding kinks, which separates dif…
Extreme values of elastic strain and energy in sine-Gordon multi-kink collisions
Aliakbar Moradi Marjaneh, Alidad Askari, Danial Saadatmand +1
In our recent study the maximal values of kinetic and potential energy densities that can be achieved in the collisions of slow kinks in the sine-Gordon model were calculated a…
High energy density spots and production of kink-antikink pairs in particle collisions
Alidad Askari, Danial Saadatmand, Sergey V. Dmitriev +1
The maximal energy density that can be achieved in the collisions of the particle-like wave trains in the model has been investigated numerically for different wave train par…
