A. Derossi et al., SYMMETRY-BREAKING INSTABILITIES OF SPATIAL PARAMETRIC SOLITONS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 56(5), 1997, pp. 4959-4962
We investigate the symmetry-breaking (temporal or transverse) instabil
ities of (1+1)- and (2+1)-dimensional two-wave parametric solitons sus
tained through the interplay of diffraction and second-harmonic genera
