Description

We study entanglement entropy in SU(2) pure gauge theory due to the presence of static quarks in $d=2+1$. Using a replica approach we investigate the $q=2$ Renyi entropy across various partitions of space $A$ and $\overline{A}$. We use Polyakov lines to define the entanglement entropy associated with a quark pair in confinement, finding this entropy scales to a finite, uniquely defined, and non-zero value in the continuum limit. We study the entanglement entropy of various sizes and locations of region $A$ relative to the quark pair and compare our results to the predictions of a string model.
