The complex Langevin (CL) method is a promising approach to overcome the sign problem, which emerges in real-time formulations of quantum field theories. Over the past decade, stabilization techniques for CL have been developed with important applications in finite density QCD. However, they are insufficient for SU( 𝑁 𝑐 ) gauge theories on a Schwinger-Keldysh time contour that is required for a real-time formulation. In these proceedings we revise the discretization of the real-time CL equations…

Kernel controlled real-time Complex Langevin simulation

This study explores the utility of a kernel in complex Langevin simulations of quantum real-time dynamics on the Schwinger-Keldysh contour with the 0 + 1 dimensional anharmonic oscillator using m = 1; λ = 24, which was previously unattainable using thecomplex Langevin equation.

Towards learning optimized kernels for complex Langevin

This work modify complex Langevin using kernels and proposes the use of modern auto-differentiation methods to learn optimal kernel values, guided by functionals encoding relevant prior information, such as symmetries or Euclidean correlator data.

The determination of real-time dynamics of strongly coupled quantum fields is a central goal of modern nuclear and particle physics, which requires insight into quantum field theory beyond the



Lattice simulations of real-time quantum fields

We investigate lattice simulations of scalar and non-Abelian gauge fields in Minkowski space-time. For SU(2) gauge-theory expectation values of link variables in 3+1 dimensions are constructed by a

Stable solvers for real-time Complex Langevin

The potential of modern implicit solvers for stochastic partial differential equations in the simulation of real-time complex Langevin dynamics is explored, finding that these methods offer asymptotic stability, rendering the issue of runaway solution moot, and allow us to simulate at comparatively large Langevin time steps, leading to lower computational cost.

Dynamical stabilisation of complex Langevin simulations of QCD

The ability to describe strongly interacting matter at finite temperature and baryon density provides the means to determine, for instance, the equation of state of QCD at non-zero baryon chemical

Argument for justification of the complex Langevin method and the condition for correct convergence

The complex Langevin method is a promising approach to the complex-action problem based on a fictitious time evolution of complexified dynamical variables under the influence of a Gaussian noise.

Justification of the complex Langevin method with the gauge cooling procedure

Recently there has been remarkable progress in the complex Langevin method, which aims at solving the complex action problem by complexifying the dynamical variables in the original path integral. In
