Entanglement in a Maxwell theory coupled to a non-relativistic particle
Abstract
Abstract We consider electromagnetism in a cylindrical manifold coupled to a non-relativistic charged point-particle. Through the relation between this theory and the Landau model on a torus, we study the entanglement between the particle and the electromagnetic field. In particular, we compute the entanglement entropy in the ground state, which is degenerate, obtaining how it varies in the degeneracy subspace.
