Quantum Coherent Transport in Atoms & Electrons
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
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
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...
NEMO5: Why must we treat topological insulator nanowires atomically?
15 Oct 2015 | | Contributor(s):: Fan Chen, Michael J. Manfra, Gerhard Klimeck, Tillmann Christoph Kubis
IWCE 2015 presentation. Abstract and more information to be added at a later date.
Tutorial Introduction to Topological Insulators
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...
Spin Transport and Topological Insulators I
29 Aug 2011 | | Contributor(s):: Supriyo Datta
A major development of the last two decades, the physical and conceptual integration of what used to be two distinct unrelated fields, namely spintronics and magnetics.

How to Turn Graphene into a Robust Topological Insulator Using Adatoms
12 Jul 2011 | | Contributor(s):: Jason Alicea
In this talk I will discuss a recent proposal for generating a robust TI state in a more readily available two-dimensional system -- graphene.
