he most exciting areas of research in condensed matter physics during the past decade. Even though topological band structures were originally discussed in the context of solid-state electron systems, where the quantum Hall effect and its relation to topology were first discovered, the study of topological band structures in photonic and classical mechanical systems are also nowadays of great research interest. In this talk, I first give a general overview of topological band structures, and then discuss their manifestations in photonic and classical mechanical setups in the presence of external drive and dissipation. I explain how an analog of the integer quantum Hall effect can be observed in the driven-dissipative setup, and show that such a driven-dissipative Hall effect can be a powerful tool to measure the geometry and topology of photonic and mechanical band structures.
