Physics and Astronomy Colloquium

Thursday, March 31st 2016
3:35 pm:
Speaker: Abhay Pasupathy, Columbia University
Subject: Experiments in Flatland
Refreshments to be served outside 101 Fraser after the colloquium.

In the past decade, scientists have figured out how to create and probe crystalline materials that are a single or few atomic layers in thickness. These two-dimensional (2D) materials have a host of new physical, chemical and mechanical properties. The most well-known member of this family is graphene, but in the past few years we have been able to synthesize a whole host of 2D materials including semiconductors, superconductors, magnets, charge density waves, and so on. In this talk, I will present some of my research group's experimental exploration of these materials. In particular, I will discuss the following topics (a) how one can induce spatially ordered phases in graphene (b) what happens to a crystalline superconductor when we take it to the 2D limit (c) ways in which complex phases like charge density waves can be tuned in 2D samples.
