We numerically study the intrinsic localized vibrational modes in a diatomic chain with different masses and alternating force constants between nearest neighbors.This model simulates a row of atoms in the<111>directi...
For a monatomic one-dimensional chain of particles interacting via a nearest-neighbor purely anharmonic potential of any even order(such a chain is called purely anharmonic chain),it is proved that there really exist ...
