New three-dimensional two-component solitons were predicted. Depending on spectral conditions, these can form hole-vortex defects or bright bullets, with stability analyzed using a variational approach in uniaxial crystals.

Area of Science:

  • Nonlinear optics
  • Soliton physics
  • Wave propagation

Background:

  • Two-component solitons are crucial in nonlinear systems.
  • Long-short wave resonance mode presents unique propagation dynamics.
  • Understanding soliton structures and stability is key for applications.

Purpose of the Study:

  • To predict and characterize three-dimensional two-component solitons.
  • To investigate the influence of spectral properties on soliton transverse structure.
  • To estimate the stability regions of these novel soliton types.

Main Methods:

  • Theoretical prediction of solitons in long-short wave resonance.
  • Analysis of transverse structures based on spectral characteristics (normal dispersion).
