Joule-Thomson Cooling in Graphene

Abstract

Electrons in graphene exhibit hydrodynamic behavior in a certain range of temperatures. We indicate that electric current in this regime can result in cooling of electron fluid due to the Joule-Thomson effect. Cooling occurs in the Fermi liquid regime, while for the Dirac fluid the effect results in heating.
