With the advent of quantum computers and the recent developments in tensor network methods, Hamiltonian Lattice Gauge Theories have gained renewed interest: The quest is to find efficient formulations of (non-)Abelian lattice gauge theories, which can be facilitated in current and future Hamiltonian simulations. The promise is the ability to investigate problems not accessible to stochastic simulation methods, such as systems at non-zero matter density, topological terms or realtime phenomena. The workshop aims to bring researchers working on these questions together and discuss the most recent algorithmic and methodological developments as well as results for various applications in the field.
