[Journal & News] No heat flow in charge-neutral monolayer/bilayer graphene is observed

In this journal club, I briefly go through the two recent experiments (published on Nature Physics Oct. 29, 2024) showing that no heat transport in the charge-neutral monolayer and bilayer graphene in an external magnetic field.
