Upper threshold for stability of multipole-mode solitons in nonlocal nonlinear media
Zhiyong Xu, Yaroslav V. Kartashov, Lluis Torner
We address the stability of multipole-mode solitons in nonlocal Kerr-type nonlinear media. Such solitons comprise several out-of-phase peaks packed together by the forces acting be…
Soliton mobility in nonlocal optical lattices
Zhiyong Xu, Yaroslav V. Kartashov, Lluis Torner
We address the impact of nonlocality in the physical features exhibited by solitons supported by Kerr-type nonlinear media with an imprinted optical lattice. We discover that nonlo…
Soliton topology versus discrete symmetry in optical lattices
Yaroslav V. Kartashov, Albert Ferrando, Alexey A. Egorov +1
We address the existence of vortex solitons supported by azimuthally modulated lattices and reveal how the global lattice discrete symmetry has fundamental implications on the poss…
Stable three-dimensional solitons in attractive Bose-Einstein condensates loaded in an optical lattice
D. Mihalache, D. Mazilu, F. Lederer +4
The existence and stability of solitons in Bose-Einstein condensates with attractive inter-atomic interactions, described by the Gross-Pitaevskii equation with a three-dimensional…
Stable spatiotemporal solitons in Bessel optical lattices
D. Mihalache, D. Mazilu, F. Lederer +4
We investigate the existence and stability of three-dimensional (3D) solitons supported by cylindrical Bessel lattices (BLs) in self-focusing media. If the lattice strength exceeds…
Reconfigurable soliton networks optically-induced by arrays of nondiffracting Bessel beams
Zhiyong Xu, Yaroslav V. Kartashov, Lluis Torner
We address the propagation of solitons in reconfigurable two-dimensional networks induced optically by arrays of nondiffracting Bessel beams in Kerr-type nonlinear media. We show t…
Reconfigurable directional couplers and junctions optically induced by nondiffracting Bessel beams
Zhiyong Xu, Yaroslav V. Kartashov, Victor A. Vysloukh +1
We put forward the concept of reconfigurable structures optically induced by mutually incoherent nondiffracting Bessel beams in Kerr-type nonlinear media. We address collinear coup…
