SUMMARY:MSE Seminar: "Topological Physics: from Photons to Electrons"
DESCRIPTION:There are many intriguing physical phenomena that are associated with topological features — global properties that are not discernible locally. The best-known examples are quantum Hall effects in electronic systems\, where insensitivity to local properties manifests itself as conductance through edge states which are insensitive to defects and disorder. In this talk\, Dr. Hafezi will first discuss how similar physics can be explored with photons; specifically\, how various topological models can be simulated in various photonics systems\, from ring resonators to photonic crystals. He then will discuss that the integration of strong optical nonlinearity can lead to unique bosonic phenomena\, such as topological frequency combs\, topological source of quantum light and chiral quantum optics. These results may enable the development of classical and quantum optical devices with built-in protection for next-generation optoelectronic and quantum technologies. In the end\, Dr. Hafezi will cover the topological interplay between photonic and electronic systems. Specifically\, he investigates how light can create and manipulate topological states of electrons.
