Abstract
We numerically study spin turbulence ST in spin1 spinor BoseEinstein condensates with ferromagnetic and antiferromagnetic interaction by solving the GrossPitaevskii equation In the previous study for ST with ferromagnetic interaction the directions of the spin density vectors were found to be spatially disordered but temporally frozen This behavior of ST is similar to that of spin glass In this study to characterize the “spinglasslike” behavior we calculate the order parameter of the spin glass In ST with ferromagnetic interaction we confirm the growth of the order parameter which indicates that ST behaves like spin glass On the other hand in ST with antiferromagnetic interaction the order parameter does not grow This means that spin density vectors temporally fluctuate not being frozen
