Columbia researchers observe exotic quantum particle in bilayer graphene

Columbia researchers observe exotic quantum particle in bilayer graphene 10/15/2017 11:21 AM EDT A Columbia University team 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, such as emergence, quasi-particle formation, quantization, and even superconductivity."
