„Decomposition and Thermalization of Gauge Theories”.
Andreas Schaefer (Regensburg, Germany)
Summary
The decay and thermalization of isolated many-particle quantum states are studied in various subfields of physics, including high-energy physics. One of the most interesting phenomena is heavy ion collisions, which can be holographically linked to string theory in anti-de Sitter space and have very detailed data. After a general introduction, I will focus on the question of whether SU(N) gauge theories behave as predicted by the Eigenstate Thermalization Hypothesis (ETH). To answer this question, we performed simulations for low-dimensional SU(2) gauge theories on digital computers (arXiv: 2308.16202), which yielded encouraging results. As ETH makes predictions for energy, a natural theoretical approach to study e.g. Thermalization of QCD is a numerical simulation of Hamiltonian lattice QCD on quantum computers, although it is not yet feasible. Investigating the validity of ETH on digital computers is an initial step in this direction.
