Report summary

For Stanford University Department of Applied Physics in 2015-2026, the graph shows 70 visible PIs and 142 internal PI collaborations. The main research signal is Physics and Astronomy as the leading field (33% of slots across 45 PIs; 45 labels), Atomic and Molecular Physics, and Optics as the leading subfield (19% of slots across 31 PIs; 31 labels), and Photonic and Optical Devices as the leading topic (4% of slots across 8 PIs; 8 labels). That is a healthy pattern, with enough links to reveal several interpretable groups rather than one undifferentiated component. The most prominent PIs by weighted works are Shanhui Fan (209.9 weighted works; Photonic and Optical Devices, Thermal Radiation and Cooling Technologies). The clearest collaboration lines are M. M. Fejer and Marc Jankowski (39 shared works, weight 18.8). The strongest breakdown groups are group 1 with 7 PIs, 6 internal connections, weight 18, around Materials Chemistry, Atomic and Molecular Physics, and Optics, Electronic, Optical and Magnetic Materials, led by Jennifer A. Dionne, Jonathan A. Fan, Eric Pop; group 2 with 7 PIs, 6 internal connections, weight 62.5, around Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, Artificial Intelligence, led by M. M. Fejer, Amir H. Safavi‐Naeini, Marc Jankowski.
