We attempt to improve the transferability of structure-based coarse-graining through the utilization of the DiffCG method, with a particular focus on developing a systematic CG model of PS melts that can be transferable over a wide range of temperature. Our strategy to constructing the thermodynamically-consistent temperature-transferable CG model under the DiffCG framework is from two sides. On the one hand, information at multiple states from fine-grained MD simulation is configured as the targets to optimize the CG potentials.
