Properties of moving discrete breathers in a monoatomic two-dimensional crystal

The molecular dynamics method is applied to determine the domain of the parameters of an ansatz for defining initial conditions that lead to the excitation of fixed and moving discrete breathers in a monoatomic two-dimensional crystal with the Morse interatomic interaction. The main features of the...

Summary:The molecular dynamics method is applied to determine the domain of the parameters of an ansatz for defining initial conditions that lead to the excitation of fixed and moving discrete breathers in a monoatomic two-dimensional crystal with the Morse interatomic interaction. The main features of the effect of the parameters of the ansatz on the amplitude and velocity of discrete breathers are established.
