SimulCost: A Cost-Aware Benchmark and Toolkit for Automating Physics Simulations with LLMs
Yadi Cao, Sicheng Lai, Jiahe Huang +12
Evaluating LLM agents for scientific tasks has focused on token costs while ignoring tool-use costs like simulation time and experimental resources. As a result, metrics like pass@…
Ion-motion-driven enhancement of energy coupling and stability in relativistic laser-microchannel interaction
K. Weichman, M. VanDusen-Gross, G. Bruhaug +5
For sufficiently short relativistic-intensity laser pulses, the disparity in time scales for electron and ion motion causes ions to behave as a fixed, neutralizing background. As t…
Collimated -ray emission enabled by efficient direct laser acceleration
Kavin Tangtartharakul, Gaetan Fauvel, Talia Meir +5
We investigate the mechanisms responsible for single-lobed versus double-lobed angular distributions of emitted -rays in laser-irradiated plasmas, focusing on how direct laser…
Generation of 10 kT Axial Magnetic Fields Using Multiple Conventional Laser Beams: A Sensitivity Study for kJ PW-Class Laser Facilities
Jue Xuan Hao, Xiang Tang, Alexey Arefiev +4
Strong multi-kilotesla magnetic fields have various applications in high-energy density science and laboratory astrophysics, but they are not readily available. In our previous wor…
