Real time simulations of scalar fields with kernelled complex Langevin equation

Daniel Alvestad, Alexander Rothkopf, Dénes Sexty

Real time evolution of a scalar field theory is investigated. The severe sign problem is circumvented using the Complex Langevin equation. The naive application of the method break…

Lattice real-time simulations with learned optimal kernels

Daniel Alvestad, Alexander Rothkopf, Dénes Sexty

We present a simulation strategy for the real-time dynamics of quantum fields, inspired by reinforcement learning. It builds on the complex Langevin approach, which it amends with…

Beyond Cuts in Small Signal Scenarios -- Enhanced Sneutrino Detectability Using Machine Learning

Daniel Alvestad, Nikolai Fomin, Jörn Kersten +2

We investigate enhancing the sensitivity of new physics searches at the LHC by machine learning in the case of background dominance and a high degree of overlap between the observa…
