Effect of the Morse Potential Stiffness on the Properties of Discrete Breathers in 2D close Packed Crystal

Abstract:

The work presents a comparison of characteristics of discrete breathers (DB) excited in the close-packed two-dimensional Morse crystal with two different values of the potential stiffness parameter. The dependence of DB frequency on its amplitude for both crystals is calculated.
