摘要:

IIB型矩阵模型自1996年以来被提出作为超弦理论的非微扰定义。我们研究了一个简化的模型,它描述了非微扰使用Monte Carlo方法的IIB型矩阵模型的后期行为,我们使用复朗之万方法来克服的符号问题。我们调查的情况下,时空签名动态变化,从欧几里德在早期的洛仑兹在晚期。讨论了(3+1)维膨胀宇宙出现的可能性。

英文摘要:

The type IIB matrix model has been proposed as a non-perturbative definition of superstring theory since 1996. We study a simplified model that describes the late time behavior of the type IIB matrix model non-perturbatively using Monte Carlo methods, and we use the complex Langevin method to overcome the sign problem. We investigate a scenario where the space-time signature changes dynamically from Euclidean at early times to Lorentzian at late times. We discuss the possibility of the emergence of the (3+1)D expanding universe.
