Breaking down the magnonic Wiedemann-Franz law in the hydrodynamic regime
Ryotaro Sano, Mamoru Matsuo
Recent experiments have shown an indication of a hydrodynamic magnon behavior in ultrapure ferromagnetic insulators; however, its direct observation is still lacking. Here, we deri…

Valley hydrodynamics in gapped graphene
Ryotaro Sano, Daigo Oue, Mamoru Matsuo
Recent experiments have revealed that novel nonequilibrium states consistent with the hydrodynamic description of electrons are realized in ultrapure graphene, which hosts the vall…
