Discrete breathers assist energy transfer to ac driven nonlinear chains
Danial Saadatmand, Daxing Xiong, Vitaly A. Kuzkin +3
One-dimensional chain of pointwise particles harmonically coupled with nearest neighbors and placed in six-order polynomial on-site potentials is considered. Power of the energy so…
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…
Crossover from ballistic to normal heat transport in the lattice: If nonconservation of momentum is the reason, what is the mechanism?
Daxing Xiong, Danial Saadatmand, Sergey V. Dmitriev
Anomalous (non-Fourier's) heat transport is no longer just a theoretical issue since it has been observed experimentally in a number of low-dimensional nanomaterials, such as SiGe…
Multi-kink collisions in the model
Aliakbar Moradi Marjaneh, Vakhid A. Gani, Danial Saadatmand +2
We study simultaneous collisions of two, three, and four kinks and antikinks of the model at the same spatial point. Unlike the kinks, the kinks are asymmetric an…
