The open problem was what controlled the velocity of the electron liquid (shown as a wavy waterfront). The findings show that it is the frozen antiferromagnetism on the honeycomb lattice that sets this velocity by slowing it down as the two interact.

A new discovery explains what happens during the phase transition in Dirac materials, paving the way for engineering advanced electronics that perform significantly faster. Yale-NUS Associate Professor of Science (Physics) Shaffique Adam is the lead author for a recent work that describes a model for electron interaction in Dirac materials, a class of materials that includes graphene and topological insulators, solving a 65-year-old open theoretical problem in the process...
