Freeze-in Warm Dark Matter via Dimension-6 Operators in 3-3-1 Models
Fuwei Liu, Fujun Liu
We propose a natural resolution to the fine-tuning problem inherent in the freeze-in dark matter paradigm by embedding a sterile singlet within a 3-3-1 electroweak extension. By im…

LSTM-PINN: An Hybrid Method for Prediction of Steady-State Electrohydrodynamic Flow
Ze Tao, Ke Xu, Fujun Liu
Physics-Informed Neural Networks (PINNs) have demonstrated considerable success in solving complex fluid dynamics problems. However, their performance often deteriorates in regimes…
