In the present paper a two-phonon spectrum in the frequency region of the sum or difference of the frequencies of two optical phonons is studied. A quartic anharmonicity is investigated as a factor for damping of the one-and two-phonon states as well as a mechanism binding two phonons into a biphono

We investigate the nonlinear vibrations of nano-sized cantilever. The elastic force is considered anharmonic, deriving from a Morse potential and the nonlinearity is attributed to the Casimir force. We consider two cases, the first of viscous damping and the second of fractional damping. The soluti
The mechanism of the formation of nonlinear waves in an anharmonic and dispersive medium with a two-phonon resonance transition is suggested. It is shown that the acoustic wave with a relatively low energy has the appearance of a breather.
The dynamic behavior of a symmetric gyro with linear-plus-cubic damping, which is subjected to a harmonic excitation, is studied in this paper. The Liapunov direct method has been used to obtain the su$cient conditions of the stability of the equilibrium points of the system. By applying numerical r
