the Fermi liquid. One important difference is that electric currents in a Dirac fluid are not protected by momentum conservation, and therefore decay even in a perfectly clean system. Negatively charged electrons and positive holes flowing in opposite directions sum up to a finite electric current with zero momentum. Thus, even in the absence of impurities, pristine graphene – the prime example of a Dirac liquid – has a finite conductivity that is induced by electron-electron interactions [@Fritz2008; @Kashuba2008]. On the other hand, the energy current is proportional to the momentum density, and therefore propagates ballistically [@Mueller2009; @Foster2009]. Both phenomena, the interaction induced conductivity and the ballistic transport of energy, are relevant in the broader context of quantum criticality [@Damle1997; @Hartnoll2007; @Sheehy2007]. Several experiments addressed the unique transport properties of graphene at the charge neutrality point. A violation of the Wiedemann-Franz law was observed in Ref. [@Crossno2016], indicating the ballistic transport of energy. The interaction induced resistivity was recently measured at finite frequencies [@Gallagher2019] and showen to be in good agreement with the theoretical prediction of Ref. [@Fritz2008]. Graphene has become one of the most important host systems for electron hydrodynamics in general, extensively studied in both experiment [@Sulpizio2019; @Bandurin2018;
