Energy-Momentum Tensors with Worldline Numerics — •Marco Schäfer, Holger Gies, and Idrish Huet Hernandez — Theoretisch-Physikalisches Institut, Friedrich-Schiller-Universität Jena, Max-Wien-Platz 1, D-07743 Jena, Germany

We apply the worldline formalism and its numerical Monte-Carlo approach to computations of fluctuation induced energy-momentum tensors.

In the case of a fluctuating Dirichlet scalar this formalism allows the computation of induced energy-momentum tensors in arbitrary Casimir configurations.

Our methods can straightforwardly be used to investigate potential violations of positive-energy conditions by quantum field theories. These energy conditions are of particular interest in General Relativity where they are imposed on the energy-momentum tensor in order to avoid exotic spacetime properties.
