%X Ground state of the periodic Anderson model on a cubic lattice is investigated by mean-field calculations, with focusing on the possibility of charge ordering. We show that three different charge-ordered phases appear at 3/2 filling, which are accompanied by ferromagnetic, noncoplanar triple-Q, and ferrimagnetic order, respectively. The triple-Q magnetic order is likely stabilized by emergent geometrical frustration in the charge-ordered phase with the ordering wave vector (pi,pi,pi). We show that the nearest-neighbor hopping between localized electrons stabilizes the triple-Q phase relative to the other two phases. We also discuss the electronic structure in the triple-Q charge-ordered phase.
