We perform a direct test of the gauge-gravity duality associated with the system of N D0-branes in type IIA superstring theory at finite temperature. Based on the fact that higher derivative corrections to the type IIA supergravity action start at the order of alpha;{'3}, we derive the internal energy in expansion around infinite 't Hooft coupling up to the subleading term with one unknown coefficient. The power of the subleading term is shown to be nicely reproduced by the Monte Carlo data obtained nonperturbatively on the gauge theory side at finite but large effective (dimensionless) 't Hooft coupling constant. This suggests, in particular, that the open strings attached to the D0-branes provide the microscopic origin of the black hole thermodynamics of the dual geometry including alpha;{'} corrections. The coefficient of the subleading term extracted from the fit to the Monte Carlo data provides a prediction for the gravity side.
我们对有限温度下IIA型超弦理论中与N个D0膜系统相关的规范-引力对偶性进行了直接检验。基于IIA型超引力作用的高阶导数修正从α′³阶开始这一事实,我们在无限‘t Hooft耦合附近展开内能,直至带有一个未知系数的次主导项。结果表明,在有限但很大的有效(无量纲)‘t Hooft耦合常数下,规范理论一侧通过非微扰方式获得的蒙特卡罗数据能很好地重现次主导项的幂次。这尤其表明,附着在D0膜上的开弦为对偶几何的黑洞热力学提供了微观起源,包括α′修正。从对蒙特卡罗数据的拟合中提取的次主导项系数为引力一侧提供了一个预测。
