Description

Time and again, one encounters marvelous unifying physics that links phenomena from the most miniscule to astronomical scales. This lecture set will explore one such direction that brings together fundamentals of quantum optics, quantum Hall physics, and certain aspects of black hole dynamics. We will first establish some of the basics of quantum Hall physics and associated lowest Landau levels, and the behavior of quasiparticles in this realm in the presence of a potential landscape. We will see some deep parallels between these descriptions, and quantum optical concepts, such as coherent states and squeezing. We will then see how such phenomena translate to Hawking radiation and black hole ringdown in the astronomical realm. Finally, we will build on these concepts to explore an intriguing quantum particle that differs from the fermion and boson---the anyon,--which has recently been observed and come into the limelight.
