Lecture Title: A one-way street for light: exploring topological quantum physics with photons
Abstract: Using light is an ideal way to transmit information quickly; however, when we send light through a material, it can be backscattered and reflected by impurities and defects, reducing the efficiency of transmission. In this lecture, I will discuss how we can draw inspiration from quantum physics to engineer a “one-way street” for light along which the photons do not back-scatter but can only travel in one direction. These novel photonic systems are the analogue of the so-called "topological” quantum states that were recognised by the 2016 Nobel Prize for Physics. I will review how topological physics was first developed to understand the behaviour of electrons in solids, and now how these concepts can be applied to design interesting materials for controlling light. I will also discuss how topological photonics can open up new opportunities for pushing quantum physics even further, for example, by exploring topological effects that would only emerge in a world with more than three spatial dimensions.
