About this opportunity

The U.S. National Science Foundation Directorate for Mathematical and Physical Sciences (NSF MPS) supports multiple research programs at the frontiers of discovery in physics. Physics research supported by NSF MPS enables understanding of the fundamental aspects of nature at all scales, from the quantum effects inside atoms to the mysterious dark energy spanning the entire universe. The core research programs covered by this funding opportunity are: Atomic, Molecular, and Optical Physics - Experiment (AMO-Experiment)Atomic, Molecular, and Optical Physics - Theory (AMO-Theory)Elementary Particle Physics - Experiment (EPP-Experiment)Elementary Particle Physics, Astrophysics and Cosmology - Theory (EPP/Cosmology-Theory)Gravitational Physics Integrative Activities in Physics (IAP)Nuclear Physics - Experiment (NP-Experiment)Nuclear Physics - Theory (NP-Theory)Particle Astrophysics - Experiment (PA-Experiment)Physics of Living Systems (PoLS)Plasma Physics Quantum Information Science (QIS) The cross-cutting research programs covered by this funding opportunity are: Advanced Physics Instrumentation (API)Focused Research Hubs in Theoretical Physics (FRHTP)Physics at the Information Frontier (PIF) NSF MPS is particularly interested in intellectually ambitious and potentially transformative foundational research. Proposals need not promise a near-term product, deployment, or commercial outcome, nor need they address later-stage development to be competitive.

Portfolio context — this listing covers more than this opportunity

This opportunity is funded under Assistance Listing 47.049 (“Mathematical and Physical Sciences”), a broad federal program that made about 2554 new awards per year over the last five fiscal years (median award $329k). Those figures describe that whole portfolio — not this specific solicitation, so we don't show them as if they were this opportunity's track record.

Applicant counts per solicitation are not published by any federal agency — no one can honestly sell you that number. NSF publishes funding rates by directorate in its Merit Review Digest — source.
