Solitons on a Bessel lattice

(a) The interaction of out-of-phase solitons in the first ring of zero-order Bessel lattice. One of the solitons is set into motion at the entrance of the medium by imposing the phase twist on it. (b) The same as in column (a) but for in-phase solitons. (c) The interaction of out-of-phase solitons located in the first and second lattice rings. The soliton located in the first ring is set into motion by imposing the phase twist. Soliton angular rotation directions are depicted by arrows, while white rings denote rings of Bessel lattice where solitons are located. The distances at which intensity distributions are shown are indicated on each plot.
