在2+1维SCFT物理中寻找$AdS^{5} \times S^{5}$

Finding $AdS^{5} \times S^{5}$ in 2+1 dimensional SCFT physics

Mark Van Raamsdonk, Chris Waddell

摘要:

我们研究了在半空间上耦合到全息三维超共形场论(SCFT)的$\mathbb{R}^{3,1}$的IIB型弦论与${\cal N}=4$超对称Yang-Mills理论的对偶解.对偶几何是渐近的$AdS^5 \times S^5$与边界几何$\mathbb{R}^{2,1} \times \mathbb{R}^+$,几何世界末日(ETW)膜切断了另一半的渐近区域的庞加莱$AdS^5 \times S^5$。我们表明,通过选择适当的三维SCFT,这个ETW膜可以被推向任意远的失踪渐近区域,恢复“失踪”的一半庞加莱$AdS^5 \times S^5$。我们还表明,有3D SCFT的对偶包括一个楔形的庞加莱$AdS^5 \times S^5$的角度任意接近$π$,几何ETW膜的两侧。

英文摘要:

We study solutions of type IIB string theory dual to ${\cal N}=4$ supersymmetric Yang-Mills theory on half of $\mathbb{R}^{3,1}$ coupled to holographic three-dimensional superconformal field theories (SCFTs) at the edge of this half-space. The dual geometries are asymptotically $AdS^5 \times S^5$ with boundary geometry $\mathbb{R}^{2,1} \times \mathbb{R}^+$, with a geometrical end-of-the-world (ETW) brane cutting off the other half of the asymptotic region of the would-be Poincaré $AdS^5 \times S^5$. We show that by choosing the 3D SCFT appropriately, this ETW brane can be pushed arbitrarily far towards the missing asymptotic region, recovering the "missing" half of Poincaré $AdS^5 \times S^5$. We also show that there are 3D SCFTs whose dual includes a wedge of Poincaré $AdS^5 \times S^5$ with an angle arbitrarily close to $π$, with geometrical ETW branes on either side.
