Localized nonlinear, soliton-like waves in two-dimensional anharmonic lattices

摘要: Abstract We discuss here nano-scale size localized wave excitations, which are intrinsic traveling modes in two-dimensional anharmonic crystal lattice systems. In particular, using different initial conditions of coordinates and momenta we search for the longest lasting excitations triangular lattices. As most stable unaltered appear quasi-one-dimensional Toda-like solitons running rectilinear chains along main crystallographic axes such Furthermore, by following trace high energetic like “bubble chamber” methodology (or scanning tunneling microscopy) show how nonlinear waves appearing spontaneously heated systems can be detected followed space–time.
