This award, enabled by the partnership between NSF and the Czech Science Foundation (GACR), supports a collaboration that combines expertise from the University of Michigan, Lawrence Berkeley National Laboratory, and ELI-Beamlines in the Czech Republic to develop tools for modeling experiments at high power laser facilities. With rapid recent progress in laser technology, high-power laser facilities can generate some of the most extreme electromagnetic fields in the universe by focusing the laser light down to a tiny spot. These fields can accelerate charged particles to near the speed of light in a fraction of a million billionth of a second, producing bright, point-like sources of radiation. In such strong fields, high energy gamma-rays can spontaneously decay into pairs of matter-antimatter particles, thus creating matter from light. This project will further chart a path to studying even more extreme laser intensities, aiming to develop ways to make dense and ultrashort duration beams of antimatter.This project will develop the required theoretical tools and investigate the conditions for experiments studying strong field quantum electrodynamics phenomena. A postdoctoral researcher will integrate codes for modeling the interaction point physics. This will enable detailed studies of quantum broadening of the electron spectrum, polarization and spin effects and determining the requirements for a laser facility to study avalanche- and shower-type cascades. This will enable design of experiments at existing laser facilities, including ELI-Beamlines. The project will also chart a path to the generation and behavior of lepton-photon plasma and establish a research collaboration between the NSF ZEUS Laser Facility at the University of Michigan and ELI-Beamlines in the Czech Republic.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项由 NSF 和捷克科学基金会 (GACR) 合作支持，支持结合密歇根大学、劳伦斯伯克利国家实验室和捷克共和国 ELI-Beamlines 的专业知识的合作，开发用于建模实验的工具。高功率激光设施。 随着激光技术的快速进步，高功率激光设施可以通过将激光聚焦到一个微小的点来产生宇宙中一些最极端的电磁场。这些场可以在不到百万分之一秒的时间内将带电粒子加速到接近光速，产生明亮的点状辐射源。在如此强的场中，高能伽马射线可以自发地衰变成物质-反物质粒子对，从而从光中产生物质。 该项目将进一步规划一条研究更极端激光强度的道路，旨在开发制造密集且超短持续时间的反物质光束的方法。该项目将开发所需的理论工具并研究研究强场量子电动力学现象的实验条件。博士后研究员将集成用于模拟相互作用点物理的代码。这将使电子光谱的量子展宽、偏振和自旋效应的详细研究成为可能，并确定研究雪崩和簇射型级联的激光设施的要求。这将使现有激光设施（包括 ELI-Beamlines）的实验设计成为可能。该项目还将绘制轻子光子等离子体的产生和行为的路径，并在密歇根大学的 NSF ZEUS 激光设施和捷克共和国的 ELI-Beamlines 之间建立研究合作。该奖项反映了 NSF 的法定使命，并具有通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
