Paper Abstract

We simulate exact spatio-temporal evolutions of self-organization in KNbO3 using a reflection grating based phenomenological model, and a rigorous model including the time evolution of photovoltaic voltage. The initial phase difference of scattering waves is critical to hexagon formation. Finally, we compare the stability range for those two models.
