Description
We study the vacuum-subtracted entanglement entropy of the color flux tube between a static quark-antiquark pair in SU(2) through SU(5) (2+1)-D pure gauge theory. Using the replica trick, we examine the dependence of entanglement on temperature as well as the size and topology of the entangling region. Through analyzing these factors, we present quantitative conclusions about the nature of non-abelian flux in both confining and deconfining regimes, finding signatures of the intrinsic width as well as a new scale, the entanglement radius, that characterizes a "thickness" of the flux tube distinct from the intrinsic width.
