Nonlinear dynamics of the Frenkel-Kontorova model with impurities.
Oleg M. Braun,Yuri S. Kivshar +1 more
TL;DR: The nonlinear dynamics of the Frenkel-Kontorova (FK) model with local impurities is considered analytically, and it is demonstrated that localImpurity modes modify transport properties of one-dimensional systems, and the change of the kink diffusion coefficient depends on the character ofThe kink interaction with a separate impurity (repulsion or attraction).
Journal ArticleDOI
Effect of microscopic disorder on magnetic properties of metamaterials
Maxim V. Gorkunov,Maxim V. Gorkunov,Sergey A. Gredeskul,Sergey A. Gredeskul,Ilya V. Shadrivov,Yuri S. Kivshar +5 more
TL;DR: It is demonstrated that even a weak microscopic disorder may lead to a substantial modification of the metamaterial magnetic properties, and a 10% deviation in the parameters of the microscopic resonant elements may leadto a substantial suppression of the wave propagation in a wide frequency range.
Journal ArticleDOI
Photonic crystals for matter waves: Bose-Einstein condensates in optical lattices.
TL;DR: The band-gap spectrum and nonlinear localization of BECs in one- and two-dimensional optical lattices is described and useful parallels with the physics of coherent light waves in nonlinear photonic crystals and optically-induced photonic lattices are drawn.
Journal ArticleDOI
Near-field mapping of Fano resonances in all-dielectric oligomers
Dmitry Filonov,Alexey P. Slobozhanyuk,Alex Krasnok,Pavel A. Belov,Elizaveta Nenasheva,Ben Hopkins,Andrey E. Miroshnichenko,Yuri S. Kivshar +7 more
TL;DR: In this paper, a ring of six ceramic spheres with and without a central particle was studied and it was shown that both structures exhibit resonant suppression of the forward scattering associated with the Fano resonance originated from the excitation of magnetic dipole modes.
Journal ArticleDOI
Coupled-resonator-induced reflection in photonic-crystal waveguide structures
TL;DR: A novel effect of the coupled-resonator-induced reflection (CRIR) characterized by a very high and easily tunable quality factor of the reflection line, for the case of the inter-site coupling between the cavities and the waveguide.
