The kinetic theory of ultra-subsonic fermion systems and applications to flat band magic angle twisted bilayer graphene
The kinetic theory of ultra-subsonic fermion systems explores unique low-temperature transport physics in two-band systems with subsonic fermions ($v_F < v_p$). It predicts linear-in-$T$ resistivity down to very low temperatures, offering a new explanation for 'strange metal' behavior in flat band materials like magic angle twisted bilayer graphene.
