Nanophotonic materials, especially plasmonic metal nanostructures and excitonic semiconductor nanocrystals, have been the topic of widespread research, focusing primarily on the linear-optical properties of the individual materials. Recently, new classes of materials have begun to be explored, including hybrid plasmon-exciton nanostructures, two-dimensional materials, highly doped semiconductors, and perovskites. At the same time, focus has shifted to nonlinear response and non-equilibrium dynamics, revealing phenomena such as nonlinear Fano interference, coherent quantum dynamics, hot-carrier dynamics, and complex excited-state dynamics. These phenomena have the potential to enable a wide range of applications, including photochemistry, solar energy conversion, sensors, lasers, and photonic information processing. However, significant experimental and theoretical advances must be made before the underlying processes can be unraveled, the factors controlling the processes can be controlled, and they can be harnessed in future technologies.

This workshop aims to bring together experimentalists and theorists for a timely discussion of recent developments and challenges at the cutting edge of current research in nanophotonics. Sessions will focus on synthesis, measurement, and modeling of nanophotonic materials and the novel phenomena that can arise when they are far from equilibrium.
