We have recently pointed out that color magnetic field is generated in dense quark matter, i.e. color ferromagnetic phase of quark matter. Using light cone quantization, we show that gluons occupying the lowest Landau level under the color magnetic field effectively form a two dimensional quantum well (layer), in which infinitely many zero modes of the gluons are present. We discuss that the zero modes of the gluons form a quantum Hall state by interacting repulsively with each other, just as electrons do in semiconductors. Such a ferromagnetic quark matter with the layer structure of the gluons is a possible origin of extremely strong magnetic field observed in magnetars.
