Title: Measuring the knots and braids of non-Hermitian oscillators
Speaker: Jack Harris
Abstract: It may seem unlikely that rich mathematical structures remain to be uncovered in classical harmonic oscillators. Nevertheless, systems that combine non-reciprocity and loss have provided a number of surprises in recent years. I will describe how these systems naturally exhibit braids, knots, and other topological structures. I will also present measurements of these structures (using a cavity optomechanical system), and will describe their potential application in various control schemes. This will be a pedagogical introduction to these topics, with lots of pictures and videos!
