强耦合下AdS/CFT的数值试验

Numerical tests of AdS/CFT at strong coupling

David Berenstein, Randel Cotta, Rodrigo Leonardi

摘要:

本文用数值MonteCarlo算法研究了六个交换矩阵的大$N$矩阵模型中的各种关联函数(二点和三点函数)。这相当于一个模型的气体粒子在六个维度的限制二次潜力和对数排斥在有限的温度下,我们正在测量的领先阶非高斯性的热波动。这是N=4 SYM在强耦合下低能动力学的简化模型。我们发现强有力的证据表明,简化的矩阵模型与AdS/CFT对应中的三个点函数的对偶引力描述相匹配。

英文摘要:

We study various correlation functions (two and three point functions) in a large $N$ matrix model of six commuting matrices with a numerical Monte Carlo algorithm. This is equivalent to a model of a gas of particles in six dimensions with a confining quadratic potential and logarithmic repulsions at finite temperature, where we are measuring the leading order non-gaussianities in the thermal fluctuations. This is a simplified model of the low energy dynamics of N=4 SYM at strong coupling. We find strong evidence that the simplified matrix model matches with the dual gravitational description of three point functions in the AdS/CFT correspondence.
