Kink scattering in a Lorentz-violating ϕ6 model

The role played by a Lorentz-violating term on the outcomes of kink scattering in the model is investigated by using the Fourier spectral method. Impacts of the Lorentz-violating term on the critical velocities, the location of two-bounce windows, and the maximal values of various types of energy de...

Description
Summary:The role played by a Lorentz-violating term on the outcomes of kink scattering in the model is investigated by using the Fourier spectral method. Impacts of the Lorentz-violating term on the critical velocities, the location of two-bounce windows, and the maximal values of various types of energy densities are analyzed. Some novel features of kink-antikink collisions are discussed. The interactions between three and four kinks are also considered.
