The non-equilibrium effects induced by the energy flow that accompanies heat exchange between the system and its environment play a pivotal role in quantum information processing tasks. The information and energy that a quantum system exchange with its surroundings cause coherence decay and energy transfer. In this study, we used the non-Markovian quantum state diffusion method to study the dynamical evolution properties of coherence and energy flow in a five-qubit Heisenberg XXX spin chain system at thermal equilibrium. We examined the case in which the system was coupled to a common non-Markovian bosonic bath and introduced a pseudo-pure state as the initial state for the evolution of the system dynamics. Finally, we analyzed the effects of environmental memory effects, noise intensity, temperature, and magnetic field strength on quantum coherence and energy flow. Numerical simulation results show that, as the environmental correlation coefficient increases, the coherence of the system is enhanced. Energy flow back from the environment to the system may be feasible with the help of non-Markovian memory effects.
