Abstract
In confining theories, separating two charges results in the generation of new charges that screen the original ones. This process, known as “string breaking”, prevents isolation of individual charges and is one of the fundamental phenomena in gauge theories such as quantum chromodynamics, as well as in simpler models exhibiting confinement. In this talk, I will focus on the dynamics of string breaking in a trapped-ion quantum simulator. The breaking is observed as the string tension is gradually increased over time. For small strings, we characterize this breaking as a Landau-Zener process. For larger strings, we find that the string breaks by forming “bubbles” of flipped spins.
