Abstract

We consider the second Rényi entropy S(2) in pure lattice gauge theory with SU(2), SU(3), and SU(4) gauge groups, which serves as a first approximation for the entanglement entropy and the entropic C-function. We compare the results for different gauge groups using scale setting via the string tension. We confirm that at small distances l our approximation for the entropic C-function C(l), ...
