Abstract.
We study the dynamics of multipartite entanglement under decoherence induced by the environment consisting of a fermionic bath. Based on the algebraic measure of entanglement-negativity, we analyze the time evolution of entanglement of both pure states and mixed ones, and find that entanglement evolution depends on both bath temperature and the number of qubits of the system. A linear space SLDF which is dynamically decoupled from the environment is identified in the sense of linear entropy to symbolize the environment effect.
