Description
Gauge theories are of paramount importance in our understanding of fundamental constituents of matter and their interactions, ranging from high-energy particle physics to low-temperature quantum many-body physics. However, the complete characterization of their phase diagrams and the full understanding of non-perturbative effects are still debated, especially at finite charge density, mostly due to the sign-problem affecting Monte Carlo numerical simulations. In recent years, a complementary numerical approach, Tensor Networks (TN) methods, in strict connection with emerging quantum technologies, have found increasing applications for studying Lattice Gauge Theories (LGTs). In this talk, I will present some recent results concerning the application of TN algorithms to the study of real-time dynamics of LGTs including dynamical matter. In particular, I will focus on the case of Quantum Electrodynamics, addressing intriguing phenomena such as string-breaking, dynamical confinement and scattering effects.
