Type: oral presentation
Track: String Theory and Alternatives

Content

Solving non-perturbative, real-time dynamics of quantum field theory is big challenge. In this presentation we shall describe how Cauchy's theorem, and a sojourn into complex field-space, allows for the solution of the real-time path integral. This is achieved by showing that the Schwinger-Keldysh calculation may be split into two pieces, which ultimately guarantees a single saddle point in the Monte Carlo calculations, thus avoiding the multi-modal problem.
