Events at Physics
In the second half, I will discuss how even linear physics can surprise us with new and rich phenomena. Topological phases of matter were recognized by the 2016 Nobel Prize and are now a large subject in condensed matter physics and photonics. I will present the first applications of these ideas to plasma physics with two examples: (1) A topological gaseous plasmon polariton at the surface between a magnetized plasma and vacuum, and (2) the Reversed-Shear Alfvén Eigenmode, well known in tokamaks. The new field of topological plasma waves represents a multifaceted research frontier with fundamental questions to be addressed by theory, simulation, and experiment.
