“…These excitations are called as discrete breathers (DBs), intrinsic localized modes, vibrational solitons, or quodons [2,4,7,11,13,14,16,17,29,31,32,34,42,43,46,47,48,51,52]. In numerical studies of DBs different twobody potential models (Morse, Lennard-Jones, Born-MayerCoulomb and other potentials) have been used.…”
