Division of Physics

The National Science Foundation Division of Physics (NSF Physics) is a civilian federal entity within the NSF's Directorate for Mathematical and Physical Sciences. NSF Physics supports fundamental research in physics, from the study of subatomic particles to the exploration of the cosmos, providing grants for experimental and theoretical investigations across multiple subdisciplines of physics. The division plays a vital role in advancing scientific understanding of the physical universe while supporting educational initiatives and next-generation research infrastructure that enhances U.S. scientific competitiveness and innovation.

NSF Physics demonstrates substantial investment in cutting-edge research across numerous physics domains, with recent grants ranging from approximately $100,000 to over $1 million. A significant portion of funding supports research in quantum physics, gravitational wave detection, and high-energy particle physics. Major projects include collaborative experiments like the LEGEND-200 neutrinoless double beta decay detection, LHCb particle detection at CERN, and the SuperCDMS dark matter search experiment. The division also provides considerable support for advanced instrumentation development, including quantum sensors, electromagnetic simulation software, and specialized detectors for experimental facilities located both domestically and internationally.

Educational initiatives form another key funding priority, with multiple Research Experiences for Undergraduates (REU) sites receiving grants exceeding $125,000 each. These REU programs focus on specialized areas such as plasma physics, x-ray free electron laser technology, and general physics research experiences. The division demonstrates particular interest in supporting research that bridges theoretical and experimental approaches, as evidenced by numerous grants for computational modeling of physical phenomena. International collaborations are prominently featured, with many funded projects involving partnerships with research institutions in Europe and elsewhere, enabling U.S. researchers to participate in global scientific endeavors that require multinational resources and expertise.
