It was found that the ferromagnetic spinor BEC is an ideal candidate for the first experimental observation of MI, spin domain fragmentation, and spatiotemporal chaotic dynamics of matter waves.Keywords: Atoms; Birefringence; Computer simulation; Eigenvalues and eigenfunctions; Four wave mixing; Ground state; Hamiltonians; Numerical analysis; Optical fibers; Optical Kerr effect; Perturbation techniques; Quantum theory; Atomic optics; Bose-Einstein condensModulational instability of spinor condensates20012015-12-10
