arXiv:2607. 10366v1 Announce Type: new Abstract: 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 where predictions become unreliable.
Inertial confinement fusion (ICF) is a leading pathway toward clean energy, but each shot at the National Ignition Facility costs on the order of one million dollars, making accurate AI surrogates a h...

The paper introduces the ICF Laser Pulse Shape Design System (LPDS), a generative inverse modeling framework that directly maps desired fusion outcomes and pellet configurations to optimized laser pulse shapes. It incorporates a multi-objective loss function to enforce physical constraints and experimental requirements, and offers tools such as constraint-conditioning, inpainting, and gradient-based editing for fine-grained pulse control. The authors also demonstrate the framework’s applicability to a limited set of real experimental shots, positioning LPDS as a data-driven approach to advance practical inertial confinement fusion.

The paper introduces Differentiable Diffusion Conditioning (D2C), an offline model‑based optimization approach that turns a frozen conditional diffusion model into a gradient‑based optimizer. By making the reverse denoising chain differentiable with respect to conditioning signals, D2C optimizes conditioning variables using gradients from surrogate objectives and physics‑informed penalties. The method is evaluated on laser pulse optimization for inertial confinement fusion, sustainable data‑center workload scheduling, and four Design‑Bench tasks, achieving top results on the real‑world tasks and the best average rank across the benchmarks.
arXiv:2604. 01349v4 Announce Type: replace Abstract: Reservoir simulation workflows face a fundamental data asymmetry: input parameter fields (geostatistical permeability realizations, porosity distributions) are free to generate in arbitrary quantities, yet existing neural operator surrogates require large corpora of expensive labeled simulation trajectories and cannot exploit this unlabeled structure.
arXiv:2604. 01313v2 Announce Type: replace Abstract: High-fidelity simulations and complex inverse problems, such as detector modeling and unfolding, are computationally intensive bottlenecks across subatomic physics, yet essential for accurate physical interpretation.
The paper investigates why latent neural surrogate solvers, which compress physical system dynamics into a lower‑dimensional space, often fail during long‑horizon autoregressive rollouts. It demonstrates that training the latent representation only for reconstruction leads to instability, and proposes a set of training interventions—Koopman operator learning, Hamming noise injection, and multi‑step rollout fine‑tuning—that align the latent space with long‑horizon forecasting. These interventions reduce long‑rollout error by about 40 % and achieve accuracy comparable to full‑resolution models while using far fewer floating‑point operations and GPU memory, enabling stable extrapolation in mesoscale crystal‑plasticity simulations of high‑cycle fatigue.
