Co4ICF: Co-evolving Physics-Informed Surrogate and RL-based Pulse Optimizer for Inertial Confinement Fusion
Jiatong Zhao, Tengyue Zhang, Yuhan Wang +2
Offline-trained surrogates for Inertial Confinement Fusion (ICF) suffer a well-known failure mode that iterative optimizers drive inputs into out-of-distribution (OOD) regions wher…
Optimization of Laser Irradiation Uniformity for the Double-Cone Ignition Scheme with MULTI-3D simulations
Yicheng Wang, Yiwen Yang, Fuyuan Wu +3
The double-cone ignition (DCI) scheme holds a promising perspective for laser driven fusion energy and astrophysics. However, optimizing the laser irradiation uniformity under the…
Engulfment of Eccentric Planets by Giant Stars: Hydrodynamics and Light Curves
Mengqi Yang, Dong Lai, Fuyuan Wu +1
Recent observations suggest that planetary engulfment by a giant star may produce radiation that resembles subluminous red novae. We present three-dimensional hydrodynamical simula…
Accessing thermonuclear detonation with the shock front induced by the alpha particle deposition
Bohan Shen, Junjue Liao, Renjie He +3
The detonation behaviors during thermonuclear burning indicate a state of robust hot spot burning and are widely present in astronomical phenomena, such as supernovae. In this work…
