New Particle Searches with Nonlinear Optics

Explore groundbreaking research in particle physics and optics through this comprehensive lecture by Fermilab's Quantum Theory Department head, Roni Harnik. Delve into innovative physics models including axions and dark photons as extensions to optics, and discover novel approaches to particle searches using optical techniques. Learn about "Dark SPDC," a fascinating process where pump photons convert to invisible particles and signal photons, drawing parallels to missing energy signals in collider experiments. Understand the detailed calculations of dSPDC rates in waveguides, system parameter scaling, and emerging opportunities for dark matter detection using optical tools. Benefit from Harnik's extensive expertise, developed through his academic journey from Berkeley to SLAC, Stanford, and ultimately Fermilab, where he now leads quantum theory research and the SQMS NQI Research Center.
