Our group investigates topological features in optical systems to discover new physics and develop optical devices with built-in protection.
Welcome to the Hafezi Research Group
Recent advances in nanophotonic devices have enabled a variety of new technologies, including light-based classical information processing as a promising alternative to electronic signals in future circuits, non-classical light generation, and potential avenues for quantum information sciences. Our group aims to theoretically and experimentally investigate various quantum properties of light-matter interaction for applications in quantum information processing and sensing. Moreover, we explore associated fundamental phenomena, such as many-body physics, that could emerge in such physical systems.
We explore many-body quantum dynamics of strongly interacting systems. Specifically, we investigate novel effects specific to optical systems, such as dissipative-driven phenomena.
We exploit hybrid approaches to probe and manipulate single-particle and many-body quantum states, such as optical manipulation of electronic topological states.
