Comment on "Spatial optical solitons in highly nonlocal media" and related papers
Milan S. Petrovic, Najdan B. Aleksic, Branislav N. Aleksic +2
In a recent paper [A. Alberucci, C. Jisha, N. Smyth, and G. Assanto, Phys. Rev. A 91, 013841 (2015)], Alberucci et al. have studied the propagation of bright spatial solitary waves…
Rotating solitons supported by a spiral waveguide
Milan S. Petrovic, Aleksandra I. Strinic, Najdan B. Aleksic +1
We investigate numerically light propagation in a single spiral waveguide formed in a nonlinear photorefractive medium for a low spatial frequency of the waveguide rotation. We pre…
Do shape invariant solitons in highly nonlocal nematic liquid crystals really exist?
Milan S. Petrovic, Aleksandra I. Strinic, Najdan B. Aleksic +1
We question physical existence of shape invariant solitons in three dimensional nematic liquid crystals. Using modified Petviashvili's method for finding eigenvalues and eigenfunct…
