Generic interacting many-body quantum systems are believed to behave as classical fluids
on long time and length scales. Due to rapid progress in growing exceptionally pure crystals …

A wide range of materials, like d-wave superconductors, graphene, and topological
insulators, share a fundamental similarity: their low-energy fermionic excitations behave as …

The electron–hole plasma in charge-neutral graphene is predicted to realize a quantum
critical system in which electrical transport features a universal hydrodynamic description …

We develop a two stage renormalization group which connects the continuum Hamiltonian
for twisted bilayer graphene at length scales shorter than the moire superlattice period to the …

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 …

Interactions between particles in quantum many-body systems can lead to collective
behavior described by hydrodynamics. One such system is the electron-hole plasma in …

Understanding Dirac-like fermions has become an imperative in modern condensed matter
sciences: All across the research frontier, from graphene to high T c superconductors to the …

The problem of electron-electron interactions in graphene is reviewed. Starting from the
screening of long-range interactions in these systems, the existence of an emerging Dirac …

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 …

In graphene, electron–electron interactions are expected to play a significant role, as the
screening length diverges at the charge neutrality point and the conventional Landau theory …
