Abstract: | <p>Ispitivan je generalisani Frenkel-Kontorova model pod dejstvom spoljašnjih periodičnih sila, i njihov uticaj na Šapiro stepenike. Deformacija substratnog potencijala prouzrokuje pojavu velikih polucelih i drugih subharmonijskih stepenika u sistemu. Rezultati dobijeni u radu su od značaja u talasima i spinovima gustine naboja kao i u Džozefsonovim spojevima.</p> <p>Properties of the Shapiro steps in dierent<br />commensurate structures of the ac + dc driven<br />Frenkel-Kontorova model with dierent generalized<br />substrate potential have been examined.<br />Deviation from the sinusoidal potential produces<br />appearance of large subharmonic steps.<br />Presented results could be of great importance<br />for thestudies of all real systems closely related<br />to the dissipative dynamics of the FK model<br />such as studies of the charge- or spin-density wave<br />systems and the systems of Josephson-junction arrays.</p> |
