Strongly isotropy irreducible spaces whose Laplacians have all their eigenspaces irreducible
Emilio A. Lauret, Fiorela Rossi Bertone
Let be a closed subgroup of a compact connected Lie group such that is simply connected, the action of on is almost effective, and is a strongly isotr…
Learn the Dynamics, Enforce the Physics: Generative Latent Operators for High-Dimensional Beam Evolution
Haohan Zou, Alexander Scheinker, Yuanyuan Shi
Particle-in-cell (PIC) simulation is indispensable for modeling beam dynamics in particle accelerators, but its computational cost limits many-query workflows, such as configuratio…
Gradient-Free Sampling from Generative Models via Stochastic Bounded Extremum Seeking
Alexander Scheinker
We introduce a sampling approach for energy- and score-based generative models that requires no gradient evaluations of the model. Replacing the drift term that would normally cont…
Sim+Real: Joint Simulation-Experiment Training Improves Balanced Prediction in Physical Systems
Mahindra Rautela, Alexander Scheinker, Ayan Biswas +3
Simulation and experimental measurements provide complementary data for learning spatiotemporal physical systems, but standard simulation-to-experiment fine-tuning optimizes only t…
