A Landau level basis leads to an equivalent spin-boson model that couples adjacent Landau levels. We study the entanglement between the spin and orbital subspaces in the ground state of a gas of electrons described by this Hamiltonian. The spin-orbit entanglement entropy as a function of filling factor is piecewise smooth with discontinuous derivatives due to gapped levels of degenerate orbitals and level crossings.}, url = {http://pcs.ibs.re.kr/PCS_Workshops/PCS_NLST2017.html}, author = {Francis N.
