摘要:

给出了有限温度下16个超荷超对称矩阵量子力学的第一个Monte Carlo结果。最近提出的非晶格模拟,使我们能够包括在一个透明的和可靠的方式费米子矩阵的影响。内能很好地插值了由高温膨胀得到的弱耦合行为和从对偶黑洞几何预测的强耦合行为。的Polyakov线采取大的值,即使在低温下表明的相变的情况下,形成鲜明对比的玻色子的情况下。这些结果为规范/引力对偶性提供了高度非平凡的证据。

英文摘要:

We present the first Monte Carlo results for supersymmetric matrix quantum mechanics with sixteen supercharges at finite temperature. The recently proposed non-lattice simulation enables us to include the effects of fermionic matrices in a transparent and reliable manner. The internal energy nicely interpolates the weak coupling behavior obtained by the high temperature expansion, and the strong coupling behavior predicted from the dual black hole geometry. The Polyakov line takes large values even at low temperature suggesting the absence of a phase transition in sharp contrast to the bosonic case. These results provide highly non-trivial evidences for the gauge/gravity duality.
