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.

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

 A 3D topological insulator (TI) has a fully gapped insulating bulk state but a conducting surface. Such conducting “surface” 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.

Abstract: 

Special Seminar featuring Wenchao Xu, MIT

Photons interact weakly in vacuum. Finding an optical medium that manifests optical nonlinearity at individual photon level is fascinating, as it opens the possibility to build up all-optical quantum devices, and form novel quantum many-body states of lights.

Nicole Yunger Halpern, Harvard University

Thermodynamics has shed light on engines, efficiency, and time’s arrow since the Industrial Revolution. But the steam engines that powered the Industrial Revolution were large and classical. Much of today’s technology and experiments are small-scale, quantum, far from equilibrium, and processing information.

Due to the APS March Meeting being canceled, IQC has scheduled a mini-symposium for University of Waterloo students to give their accepted talks.

Talks are open for all to attend.

Liyuan Qiu, Institute for Interdisciplinary Information Sciences, Tsinghua University

In this talk, I will introduce three non-equilibrium dynamics experiments in the anti-ferromagnetic spin-1 sodium condensate, including one experiment about the Kibble-Zurek mechanism in the first-order quantum phase transition and two experiments about Dynamical Quantum Phase Transitions.

In the Kibble-Zurek mechanism, we find out that not only the ground state matters in quantum phase transition but also the high excited states matter.

Please join us for the first virtual seminar of 2021 on Thursday, January 14th at 11:00 am.
