摘要：
Quantum dynamics of a central single-qubit system under quantum Heisenberg XY interaction, in a layered fermionic environment, is studied. Also we discuss it's time evolution in the presence of finite and infinite number of environmental spins. Finally, using the Nakajima-Zwanzig and the time-convolutionless projection operator techniques to the generalized spin star model, the exact time evolution of the reduced density operator is derived.
