Recent developments on the black hole information problem have shown how tools like the quantum extremal surface prescription and entanglement wedge reconstruction may be used to obtain a Page curve and reproduce the Hayden-Preskill decoding criterion. This poster is based on work where we applied these tools to study information recovery from black holes in a simple model of 2d gravity. We...
We present the Worldline Monte Carlo method, a direct numerical evaluation of quantum mechanical path integrals. We prove the validity of the method by simulating the QED effective action and we illustrate some improvements to the sampling trajectories with a quantum mechanical system. Finally, we discuss a numerical implementation for the evaluation of Grassmann path integrals with the aim of...
In this contribution I will discuss how lattice simulations can be used to determine thermodynamic properties of physics beyond the standard model. Using the density of states method I analyse deconfinement in $Sp(4)$ pure Yang-Mills theory and demonstrate it's first order nature through the characteristic swallow-tail structure in the free-energy.
Over the past few years, the notion of global symmetry in quantum field theory has undergone a vast generalisation. This includes higher group symmetries as well as more exotic non-invertible symmetries. In my poster, I will try to motivate this generalised notion of symmetry and provide simple examples.
My PhD project aims to enhance the Parton shower simulation of the Herwig event generator, which is used by particle physicists at the Large Hadron Collider to generate simulated data for comparing detector results and testing new models. My objective is to update the dipole parton shower to account for global recoil. This will make the simulation next to leading logarithmically accurate for...
