Report summary

The 2018-2020 picture for Yale University Department of Applied Physics is a 14-PI network with 8 internal PI collaborations. The main research signal is Physics and Astronomy as the leading field (33% of slots across 9 PIs; 9 labels), Atomic and Molecular Physics, and Optics as the leading subfield (18% of slots across 6 PIs; 6 labels), and Advanced Fiber Laser Technologies as the leading topic (10% of slots across 4 PIs; 4 labels). This is a solid, readable collaboration map: group-level fit matters more than a single department-wide label. The leading PI names are Hui Cao (29.8 weighted works; Advanced Fiber Laser Technologies, Random lasers and scattering media). The clearest collaboration lines are Peter T. Rakich and Eric A. Kittlaus (15 shared works, weight 8.7); Peter T. Rakich and Prashanta Kharel (11 shared works, weight 7.8). The leading breakdown groups are group 1 with 5 PIs, 7 internal connections, weight 20.8, around Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, Condensed Matter Physics, led by Peter T. Rakich, Prashanta Kharel, Eric A. Kittlaus.
