Breaking Time-Reversal Symmetry for Microcavity Polaritons

Explore groundbreaking research on breaking time-reversal symmetry for microcavity polaritons in this 53-minute conference talk from APS Physics. Delve into the world of photonic lattices and their potential for studying condensed-matter phenomena in optics, including topological phases of matter. Learn about the challenges of implementing Hamiltonians with broken time-reversal symmetry and discover how researchers demonstrated this effect in GaAs-based micropillars without external magnetic fields. Understand the creation of optical Zeeman splitting for polaritons and its combination with optical spin-orbit coupling, resulting in the emission of vortex beams with defined chirality. Gain insights into the potential applications of these findings in fabricating polariton lattices and exploring topological Chern phases. Join Alberto Amo from Université Lille as he presents the research and engages in a live Q&A session moderated by PRResearch Editorial Board Member Raphael Butte.
