Quantum Coherent Transport in Atoms & Electrons
Online Presentations | 21 Jun 2017 | Contributor(s):: Yong P. Chen
I will discuss some recent experimental examples from my lab studying quantum coherent transport and interferometry in electrons as well as cold atoms. For example, phase coherent electron transport and interference around a cylinder realized in a nanowire of topological insulator...

Building a Topological Quantum Computer 101
Online Presentations | 20 Jun 2017 | Contributor(s):: Michael Freedman
Michael Freeman shares his perspective on how we should approach building a quantum computer, starting with the mathematical roots and moving through the physics to concrete engineering and materials growth challenges on which success will hinge. He will then discuss a new, enhanced,...

Topological Spintronics: from the Haldane Phase to Spin Devices
Online Presentations | 31 Jan 2017 | Contributor(s):: Nitin Samarth
e provide a perspective on the recent emergence of “topological spintronics,” which relies on the existence of helical Dirac electrons in condensed matter. Spin‐ and angle‐resolved photoemission spectroscopy shows how the spin texture of these electronic states can be engineered using...

Tutorial Introduction to Topological Insulators
Online Presentations | 08 May 2014 | Contributor(s):: Parijat Sengupta
An important pursuit in semiconductor physics is to discover new materials to sustain the continuous progress and improvements in the current electronic devices.Traditionally, three material types are in use: 1) Metals 2) Semiconductors 3) Insulators. All the three material types are classified...
