Entanglement entropy as a witness of the Aharonov-Bohm effect in QFT

We study the dependence of the entanglement entropy with a magnetic flux and show that the former quantity witnesses an Aharonov-Bohm-like effect. In particular, we consider free charged scalar and Dirac fields living on a two-dimensional cylinder and study how the entanglement entropy for a strip-l...

Zusammenfassung:We study the dependence of the entanglement entropy with a magnetic flux and show that the former quantity witnesses an Aharonov-Bohm-like effect. In particular, we consider free charged scalar and Dirac fields living on a two-dimensional cylinder and study how the entanglement entropy for a strip-like region on the surface of the cylinder is affected by a magnetic field enclosed by it.
