Classical and Quantum Simulation of (2+1) D Abelian and non-Abelian String Dynamics

Understanding the real-time dynamics of string dynamics in lattice gauge theory (LGT) formulism from a first-principles approach remains an outstanding challenge in high-energy physics. In this talk, I will introduce our newly developed analytical and numerical tools for string dynamics with applications to the prototype Abelian and non-Abelian LGT, i.e., Fradkin-Shenkar model and SU(2) quantum link model. We are able to uncover the underlying mechanism of several intriguing phenomena, such as dynamical phase transitions, string breaking, glueball formation, and baryon blockade. The many-body magic transition as a probe of string breaking will also be covered. Lastly, I will discuss the realization of such dynamics in a near-term trapped-ion quantum computer and error mitigation (correction) protocols.
