摘要:

我们证明了ABJM理论,这是一个N=6的超共形U(N)*U(N)Chern-Simons规范理论,可以通过应用一个简单的Monte Carlo方法来研究任意N和任意耦合常数的矩阵模型,该模型可以通过使用本地化技术从理论导出。这为在量子水平上研究M理论和检验AdS_4/CFT_3对偶性提供了可能。在这里,我们计算自由能,并确认N^{3/2}标度在M理论极限预测从重力方面。我们还发现,我们的结果很好地插值的分析公式提出以前的M-理论和IIA型制度。此外,我们表明,由费米气体的方法得到的一些结果可以清楚地理解,从常数的地图的贡献得到的亏格展开。该方法可以很容易地推广到BPS算子的计算和其他理论,减少到矩阵模型。

英文摘要:

We show that the ABJM theory, which is an N=6 superconformal U(N)*U(N) Chern-Simons gauge theory, can be studied for arbitrary N at arbitrary coupling constant by applying a simple Monte Carlo method to the matrix model that can be derived from the theory by using the localization technique. This opens up the possibility of probing the quantum aspects of M-theory and testing the AdS_4/CFT_3 duality at the quantum level. Here we calculate the free energy, and confirm the N^{3/2} scaling in the M-theory limit predicted from the gravity side. We also find that our results nicely interpolate the analytical formulae proposed previously in the M-theory and type IIA regimes. Furthermore, we show that some results obtained by the Fermi gas approach can be clearly understood from the constant map contribution obtained by the genus expansion. The method can be easily generalized to the calculations of BPS operators and to other theories that reduce to matrix models.
