SUMMARY:Photonic Pseudomagnetism and Landau Levels - Mikael Rechtsman\, Pe

DESCRIPTION:When electrons moving in a two-dimensional plane are subject t
 o a perpendicular magnetic field they move in circles called cyclotron orb
 its as a result of the Lorentz force.  Treated quantum mechanically\, thes
 e orbits become quantized like the orbitals of an atom\, forming highly de
 generate states called Landau levels.  In this talk\, I will show how we m
 ade photons "feel" a magnetic field and thus form Landau levels in a photo
 nic crystal\, despite the fact that photons carry no charge and thus canno
 t experience the Lorentz force.  This increases the strength of interactio
 n between light and matter\, which has implications in quantum optics and 
 integrated photonics.  Time permitting\, I will discuss the related topic 
 of how edge states in a "Chern insulator" photonic crystal can be used to 
 slow down light in a photonic chip over a wide bandwidth.\n
