We construct and analytically compute entanglement and the R\'enyi entropiesof Dirac fermions on a 2 dimensional torus in the presence of backgroundchemical potential, current source and Wilson loop, by employing correlationfunctions of the electromagnetic vertex operators of $\mathbb{Z}_n$ orbifoldtheory. The entropies reveal numerous novelties. They probe the energy levelsof compact fermions through the chemical potential, demonstrate interferencephenomena with the current source being `beat frequency,' and experiencetopological phase transitions by dialing the Wilson loop, in the lowtemperature limit. In the large radius limit, they depend only on the Wilsonloop via topological transitions, which are tightly linked to conformaldimension of the electromagnetic operators.
