Columbia researchers observe exotic quantum particle in bilayer graphene


October 6, 2017

A Columbia University team led by assistant professor Cory Dean has definitively observed an intensely studied anomaly in condensed matter physics--the even-denominator fractional quantum Hall state--via transport measurement in bilayer graphene. "Observing the 5/2 state in any system is a remarkable scientific opportunity, since it encompasses some of the most perplexing concepts in modern condensed matter physics," says Dean. Full Story

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
