Abstract
Aim. An attempt is made to find how the combination of the mass of an atom of hydrogen and helium (taking into account its isotopes) and its polarizability affect the movement of a Frenkel‒Kontorova soliton.
Methodology. Use is made of the relations (previously obtained by the authors) to relate the characteristics of the atom with the characteristics of the lattice through which the soliton moves.
Results. A strong relationship is found between the mass of an atom and its polarizability, which determines the soliton structure.
Research implications. It is shown that the possibility of moving a soliton is determined by both the mass of the atom and its polarisability; for example, due to polarizability, a helium atom will not move.
