Report summary

The 2021-2023 picture for University of California, San Diego Department of Physics is a 50-PI network with 10 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (39% of slots across 32 PIs; 32 labels), Nuclear and High Energy Physics as the leading subfield (14% of slots across 15 PIs; 15 labels), and Particle physics theoretical and experimental studies as the leading topic (5% of slots across 7 PIs; 7 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 (24.1 weighted works; High-pressure geophysics and materials, Physics of Superconductivity and Magnetism). The strongest pairings are Yi‐Zhuang You and Da-Chuan Lu (4 shared works, weight 4); Richa Karmakar and Wouter‐Jan Rappel (3 shared works, weight 2.5). The standout breakdown groups are group 1 with 5 PIs, 5 internal connections, weight 3.5, around Electrical and Electronic Engineering, Artificial Intelligence, Condensed Matter Physics, led by Massimiliano Di Ventra, Iván K. Schuller, M. B. Maple; group 2 with 4 PIs, 3 internal connections, weight 5.5, around Nuclear and High Energy Physics, Atomic and Molecular Physics, and Optics, Condensed Matter Physics, led by Chunhui Du, Yi‐Zhuang You, Da-Chuan Lu.
