Photonic Structures with Topological Robustness: from Classical to Quantum
09 Jan 2017   Contributor(s):: Mohammad Hafezi
In this talk, I demonstrate how similar physics can be observed for photons; specifically, how various quantum Hall Hamiltonians can be simulated in an optical platform. I report on the first observation of topological photonic edge state using silicononinsulator technology and our recent...

FewBody Insights Into the Quantum Hall Problem
05 Jan 2016 
This talk will summarize insights that emerge from theoretically treating a finite number of (38) electrons confined to a twodimensional plane with a magnetic field oriented transversely. This is the prototype system of stronglycorrelated electrons in condensed matter physics, which...

The Optical Freqency Comb: A Remarkable Tool for Metrology, Science and Medical Diagnostics
31 Dec 2008   Contributor(s):: John L. Hall
The Optical Frequency Comb concept and technology exploded in 19992000 from the synthesis of advances in independent fields of Laser Stabilization, UltraFast Lasers, and NonLinear Optical Fibers. The Comb was developed first as a method for optical frequency measurement, enabling a...

Lecture 3A: Spin Transport
20 Aug 2008   Contributor(s):: Supriyo Datta
Objective: To extend the model from Lectures 1 and 2 to include electron spin. Every electron is an elementary “magnet” with two states having opposite magnetic moments. Usually this has no major effect on device operation except to increase the conductance by a factor of two.But it is now...
