Report summary

The 2018-2020 picture for University of California, San Diego Department of Physics is a 44-PI network with 18 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (33% of slots across 27 PIs; 27 labels), Astronomy and Astrophysics as the leading subfield (10% of slots across 10 PIs; 10 labels), and Physics of Superconductivity and Magnetism as the leading topic (4% of slots across 5 PIs; 5 labels). That is a thin collaboration pattern, useful for spotting individual pairs but less persuasive as a broad departmental network. The top weighted PIs are J. E. Hirsch (12.1 weighted works; Physics of Superconductivity and Magnetism, High-pressure geophysics and materials). The strongest pairings are Iván K. Schuller and Oleg Shpyrko (3 shared works, weight 1.6). The standout breakdown groups are group 1 with 8 PIs, 9 internal connections, weight 5.5, around Electronic, Optical and Magnetic Materials, Electrical and Electronic Engineering, Biomedical Engineering, led by Richard D. Averitt, Iván K. Schuller, Oleg Shpyrko.
