Quantum Frontiers Distinguished Lecture: Crazy behaviour of light inside solids

David Snoke, University of Pittsburgh

Much of our intuition about light comes from our experience that light has very weak interaction with other light鈥攁 beam of light easily passes through another beam of light, so that the Star Wars scenes of 鈥渓ight sabers鈥 bouncing off each other are just imaginary. But in solids, the properties of light can be changed dramatically, especially in solids that we design for new effects.

Carbon based nanoelectromechanics: Physics and Applications

Sangwook Lee, Ewha Womans University

In this presentation, physical properties and possible applications of carbon based nano electro-mechanical devices (NEMS) will be introduced. Our research started from carbon nanotube based nano electro-mechanical relay structure and expanded to graphene based xylophone and drum like devices. Micro contact transfer method is applied to realize the suspended nano structures with various electrodes under the nano materials.

RAC1 Journal Club/Seminar Series

Academic Writing Workshop #4

Elisabeth van Stam (UW Writing and Communication Centre)

Join us for our last session in the clarity in scientific writing series. During this session, we will apply the principles you have learned in order to improve the clarity and cohesion of your own writing. Please bring a sample of your writing (1-2 pages, double spaced), and be prepared to read, discuss, and revise!

Topological Insulator-Superconductor Heterostructures and Devices

Lin Li, IQC

聽A 3D topological insulator (TI) has a fully gapped insulating bulk state but a conducting surface. Such conducting 鈥渟urface鈥 states are formed with helical Dirac fermions, with spin-momentum strictly locked by spin-orbital coupling. When coupled to a conventional s-wave superconductor (S), the surface state behaves just like the desired p-wave superconductor. It has been predicted that Majorana zero-modes obeying non-Abelian statistics can appear in such a system.
