论文摘要
这项研究探讨了schwinger-keldysh轮廓上量子实时动力学的复杂langevin模拟中内核的实用性。我们提供了几个示例，其中我们使用系统方案来查找可恢复复杂兰格文的正确收敛的内核。这些方案结合了我们知道的有关系统的先前信息以及复杂Langevin对构建内核的融合的正确性。这使我们可以使用$ M = 1 $，$λ= 24 $在实时Schwinger-Keldysh轮廓上模拟高达$1.5β$，以前是使用复杂的Langevin方程来实现的。
This study explores the utility of a kernel in complex Langevin simulations of quantum real-time dynamics on the Schwinger-Keldysh contour. We give several examples where we use a systematic scheme to find kernels that restore correct convergence of complex Langevin. The schemes combine prior information we know about the system and the correctness of convergence of complex Langevin to construct a kernel. This allows us to simulate up to $1.5β$ on the real-time Schwinger-Keldysh contour with the 0+1 dimensional anharmonic oscillator using $m=1$, $λ=24$, which was previously unattainable using the complex Langevin equation.
