Supersymmetry and Entanglement in the Generalized Dirac Oscillator
arXiv:2607.04348
Abstract
The supersymmetric properties of the generalized Dirac oscillator allow us to determine the entanglement entropy between the spin and the continuous variable in a purely algebraic manner. The entanglement has a relativistic origin and disappears in the nonrelativistic limit. The entanglement entropy attains its maximal value in the limit of infinite energy.
