色铁磁夸克物质中胶子的二维量子阱

Two Dimensional Quantum Well of Gluons in Color Ferromagnetic Quark Matter

Aiichi Iwazaki

摘要:

我们最近指出,色磁场是在致密夸克物质中产生的,即夸克物质的色铁磁相。利用光锥量子化方法,我们证明了在色磁场作用下,占据朗道最低能级的胶子有效地形成了一个二维量子阱(层),其中存在无穷多个胶子的零模。我们讨论了胶子的零模通过相互排斥作用形成量子霍尔态,就像半导体中的电子一样。这种具有胶子层状结构的铁磁夸克物质是磁星中观测到的极强磁场的可能来源。

英文摘要:

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.
