Abstract
In this report, the dynamical behavior of the entanglement between Dirac electrons in silicene and photons in a bimodal cavity, filled with a centrosymmetric nonlinear medium, with due attention to the first and third order susceptibilities, is investigated. The matrix representation of the total Hamiltonian is block-diagonal, each with ever-growing dimensions, is written. Choosing proper initial states, time evolution of the density operator and the negativity, as a measure of quantifying entanglement, is calculated. Our results show that, generally, the temporal behavior of the electron-photon entanglement is oscillatory, with dips and plateaus, whose characteristics depend on the agent parameters ad sometimes the collapse-revival pattern is appeared.
