Explore the fascinating world of non-Hermitian quantum physics in this 50-minute lecture by Aashish Clerk at the International Centre for Theoretical Sciences. Delve into topics ranging from sensing applications to exotic topology, covering dispersive measurements, exceptional point sensing, and the Kitaev Majorana chain. Learn about the challenges and potential of non-Hermitian systems, including fluctuation effects, signal strength, and bounds on signal-to-noise ratio. Discover how non-reciprocity can enhance sensors and gain insights into phase-dependent directionality. Conclude with a Q&A session addressing potential implementations of these concepts in real-world applications.
