双尖峰;新的尖峰弦解

Dual Spikes; New Spiky String Solutions

A. E. Mosaffa, B. Safarzadeh

摘要:

我们发现了一类新的尖峰解决方案,封闭弦平坦,$AdS_3\subset AdS_5$和$R\times S^2(\subset S^5)$背景。在平坦的情况下,新的解是Kruczenski hep-th/0410226发现的尖弦的T-对偶构型。在解存在于$AdS$中的情况下,我们采用大角动量极限进行了半经典分析。这些双尖峰的异常尺寸是类似的旋转和脉动的圆弦在AdS角动量发挥作用的水平数。这取代了众所周知的自旋弦的对数相关性。对于球上的双尖峰,我们发现不存在大的角动量极限。

英文摘要:

We find a new class of spiky solutions for closed strings in flat, $AdS_3\subset AdS_5$ and $R\times S^2(\subset S^5)$ backgrounds. In the flat case the new solutions turn out to be T-dual configurations of spiky strings found by Kruczenski hep-th/0410226. In the case of solutions living in $AdS$, we make a semi classical analysis by taking the large angular momentum limit. The anomalous dimension for these dual spikes is similar to that for rotating and pulsating circular strings in AdS with angular momentum playing the role of the level number. This replaces the well known logarithmic dependence for spinning strings. For the dual spikes living on sphere we find that no large angular momentum limit exists.
