Nick Heller, Vatche Sahakian

AI总结:

本研究将随机量子化与随机变分法结合应用于全息对偶研究,在玻色性Banks-Fischler-Shenker-Susskind矩阵理论中验证了方法有效性,计算的两点函数与格点结果吻合且捕捉到强耦合相变,为全息对偶和演生几何研究提供新途径。

摘要:

随机量子化通过对路径积分中的相空间进行随机采样,为量子可观测量的计算提供了一种替代途径。此外,若人们对强耦合下某些可观测量的形式有合理的定性猜测,随机变分法可对量子场论的强耦合区域提供解析层面的控制。在全息对偶的背景下,Yang-Mills理论的强耦合区域能够捕捉引力动力学,这可提供足够的洞见来指导随机变分假设的构建。我们在玻色性Banks-Fischler-Shenker-Susskind矩阵理论中验证了这一点:我们使用变分法计算了所有耦合取值下的两点函数,结果与格点数值计算一致,且捕捉到了强耦合下的禁闭-退禁闭相变。这为探索全息对偶和演生几何开辟了全新的可能性领域。

英文摘要:

Stochastic quantization provides an alternate approach to the computation of quantum observables, by stochastically sampling phase space in a path integral. Furthermore, the stochastic variational method can provide analytical control over the strong coupling regime of a quantum field theory -- provided one has a decent qualitative guess at the form of certain observables at strong coupling. In the context of the holographic duality, the strong coupling regime of a Yang-Mills theory can capture gravitational dynamics. This can provide enough insight to guide a stochastic variational ansatz. We demonstrate this in the bosonic Banks-Fischler-Shenker-Susskind Matrix theory. We compute a two-point function at all values of coupling using the variational method showing agreement with lattice numerical computations and capturing the confinement-deconfinement phase transition at strong coupling. This opens up a new realm of possibilities for exploring the holographic duality and emergent geometry.
