Report summary

Cornell University Department of Physics in 2024-2026 reads as a 22-PI network with 11 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (42% of slots across 18 PIs; 18 labels), Atomic and Molecular Physics, and Optics as the leading subfield (20% of slots across 11 PIs; 11 labels), and Topological Materials and Phenomena as the leading topic (8% of slots across 5 PIs; 5 labels). Overall the pattern is balanced: there is enough structure to identify active groups, while the field mix still leaves room for multiple research identities. The most prominent PIs by weighted works are Eun-Ah Kim (6 weighted works; Quantum many-body systems, Advanced Condensed Matter Physics). The strongest pairings are Kin Fai Mak and Jie Shan (14 shared works, weight 6.3). The strongest breakdown groups are group 1 with 7 PIs, 8 internal connections, weight 11, around Atomic and Molecular Physics, and Optics, Materials Chemistry, Condensed Matter Physics, led by Gregory D. Fuchs, Itai Cohen, Sunghoon Kim.
