Penn physicists fuse photons and electrons into hybrid quasiparticles to slash AI energy costs
Researchers at the University of Pennsylvania created polaritons, hybrid light-matter particles, that replace selected electronic gates in neural network accelerators. The device performed matrix multiplications at 40 femtojoules per operation versus 1 picojoule for standard CMOS, cutting energy per inference by roughly 25 times. The team used a gallium arsenide microcavity coupled to a monolayer of transition-metal dichalcogenide and measured coherent polariton propagation at room temperature.

UCSD and AI2 compress a century of climate physics into a 25-hour generative forecast
Scientists at UC San Diego and the Allen Institute for AI released Spherical DYffusion, a diffusion model that ingests ERA5 reanalysis and solves the primitive equations on an 0.25-degree spherical grid. The model generated 100-year ensembles at 6-hour resolution using 128 A100 GPUs for 25 wall-clock hours; RMSE against CMIP6 historical runs stayed below 0.8 kelvin for surface temperature. Training used classifier-free guidance with a physics-informed loss term that penalizes divergence of mass and energy.
