Title              :

Topotronics : transport in topological materials

Speaker         : Prof. Sumathi Rao, HRI, Allahabad
Date                : July 27, 2016
Time               : 4:00 PM
Venue            : Lecture Hall-1
Abstract        :

In this colloquium, I will give a brief introduction to the basic ideas of topological materials, from the quantum Hall effect to its generalisation to the quantum spin Hall effect and time-reversal invariant topological insulators. Then I will discuss the relevance of Dirac materials in condensed matter systems, leading upto novel materials such as Weyl semi-metals. Finally, I will give a brief summary of some of our recent work in this field.
