全息量子霍尔流体的涨落

Fluctuations of a holographic quantum Hall fluid

Niko Jokela, Matti Jarvinen, Matthew Lippert

摘要:

我们分析了D2-D8'模型描述的全息量子霍尔流体的中性谱。正如预期的量子霍尔态,我们发现该系统是稳定的,有间隙的,至少在大部分的参数空间,最低的激发模式是磁-旋子。此外,我们还发现了高模的磁旋子。我们表明,这些磁共振矢量和标量模式之间的水平交叉的直接后果。

英文摘要:

We analyze the neutral spectrum of the holographic quantum Hall fluid described by the D2-D8' model. As expected for a quantum Hall state, we find the system to be stable and gapped and that, at least over much of the parameter space, the lowest excitation mode is a magneto-roton. In addition, we find magneto-rotons in higher modes as well. We show that these magneto-rotons are direct consequences of level crossings between vector and scalar modes.
