D膜上新的非交换效应

New non-abelian effects on D branes

Roberto Iengo, Jorge G. Russo

摘要:

我们将迈尔斯介电效应推广到具有角动量的组态。由此产生的时间相关的N D 0膜束缚态可以解释为描述旋转模糊椭球。一个类似的解决方案也存在于一个RR磁场的存在下,我们详细研究。我们表明,对于任何有限的N,在一定的临界角动量以上是积极更有利于束缚态系统解离成一个阿贝尔配置的ND 0膜独立移动。我们在一般N的非阿贝尔D膜作用量的低能展开中研究了这个问题。在N=2的情况下,我们找到了完全非交换Born-Infeld D膜动力学的显式解,它们具有相同的结构,并证实了低能近似的特征。我们进一步研究了D弦配置表示模糊漏斗变形的磁场和旋转运动。

英文摘要:

We extend the Myers dielectric effect to configurations with angular momentum. The resulting time-dependent N D0 brane bound states can be interpreted as describing rotating fuzzy ellipsoids. A similar solution exists also in the presence of a RR magnetic field, that we study in detail. We show that, for any finite N, above a certain critical angular momentum is energetically more favorable for the bound state system to dissociate into an abelian configuration of N D0 branes moving independently. We have investigated this problem in the low-energy expansion of the non-abelian D brane action for generic N. In the case N=2 we find explicit solutions of the full non-abelian Born-Infeld D brane dynamics, which remarkably have the same structure and confirm the features of the low-energy approximation. We further study D string configurations representing fuzzy funnels deformed by the magnetic field and by the rotational motion.
