Superfluids of Light: Bose-Einstein Condensation of Polaritons
Online Presentations | 04 Feb 2019 | Contributor(s):: David W. Snoke
In this talk I will review some of this past work and present recent results, including oscillation of a polariton condensate in a one-dimensional ring trap, and polariton drag, in which electrons directly push photons in a wire.

Quantum Workshop III: LED Circuit and Device Physics
Teaching Materials | 07 Feb 2015 | Contributor(s):: Stella Quinones
A hands-on learning exercise used to illustrate the device physics of a light emitting diode (LED) in a simple resistor circuit. Students explore the photon energy of four LEDs, compare the voltage drop (or forward bias) across the LED, and explain the behavior of the LED under...
