WebbWe explore the entanglement dynamics of two qubits embedded in one-dimensional (1D) and three-dimensional (3D) photonic crystals. Our 1D results show sudden death and sudden birth of the entanglement, restricted by the initial coherence and the population in the excited state as well as the detuning. The results for the 3D crystal show … WebbIn applied mathematics, the Leslie matrix is a discrete, age-structured model of population growth that is very popular in population ecology.
