We investigate the influence of long-range interactions on the energy localization in a one-dimensional Morse chain with an impurity by molecular dynamics simulations. The energy distribution around the impurity is studied. It shows that in the high temperature limit there is no difference upon...

By means of molecular dynamics simulations we have investigated local energy excitations of impurities with different types (stiffness, size or mass) solved in a one-dimensional lattice. The basic configuration studied is that an impurity particle is imbedded into a chain which consists of host...
