Kernel controlled real-time Complex Langevin simulation

This study explores the utility of a kernel in complex Langevin simulations quantum real-time dynamics on Schwinger-Keldysh contour. We give several examples where we use systematic scheme to find kernels that restore correct convergence Langevin. The schemes combine prior information know about system and correctness construct kernel. allows us simulate up 2 β contour with 0 + 1 dimensional anharmonic oscillator using m = 1; λ 24, which was previously unattainable equation.
