Report summary

For Massachusetts Institute of Technology Department of Physics in 2015-2026, the graph shows 119 visible PIs and 159 internal PI collaborations. The dominant subject mix is Physics and Astronomy as the leading field (46% of slots across 93 PIs; 93 labels), Atomic and Molecular Physics, and Optics as the leading subfield (18% of slots across 44 PIs; 44 labels), and Topological Materials and Phenomena as the leading topic (4% of slots across 15 PIs; 15 labels). That is a healthy pattern, with enough links to reveal several interpretable groups rather than one undifferentiated component. The top weighted PIs are Jing Kong (73.7 weighted works; 2D Materials and Applications, Graphene research and applications). The most visible ties are Marin Soljačić and Ido Kaminer (56 shared works, weight 30.4); Marin Soljačić and Charles Roques‐Carmes (47 shared works, weight 26.8). The standout breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 117, around Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, Condensed Matter Physics, led by Marin Soljačić, Liang Fu, Ido Kaminer.
