As high-quality single-crystal materials used in electronic devices approach the microscale
and nanoscale, charge-transport phenomena in these devices result in inhomogeneous …

The last few years have seen an explosion of interest in hydrodynamic effects in interacting
electron systems in ultra-pure materials. One such material, graphene, is not only an …

The “flow” of electric currents and heat in standard metals is diffusive with electronic motion
randomized by impurities. However, for ultraclean metals, electrons can flow like water with …

Motivated by recent experiments on the phonon contribution to the thermal Hall effect in the
cuprates, we present an analysis of chiral phonon transport. We assume the chiral behavior …

The electron-phonon interaction is in many ways a solid state equivalent of quantum
electrodynamics. Being always present, the ep coupling is responsible for the intrinsic …

In this paper we study thermoelectric transport in interacting two-dimensional Dirac-type
systems using a phenomenological Boltzmann approach. We consider a setup that can …

Ultraclean graphene at charge neutrality hosts a quantum critical Dirac fluid of interacting
electrons and holes. Interactions profoundly affect the charge dynamics of graphene, which …

We develop a unified theory for second sound in two-dimensional materials. Previously
studied drifting and driftless second sound are two limiting cases of the theory …

The flow of charge and entropy in solids usually depends on collisions decaying
quasiparticle momentum. Hydrodynamic corrections can emerge, however, if most collisions …

Whereas electron-phonon scattering relaxes the electron's momentum in metals, a perpetual
exchange of momentum between phonons and electrons may conserve total momentum …
