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 low-energy excitations of graphene are relativistic massless Dirac fermions with
opposite chiralities at valleys K and K′. Breaking the chiral symmetry could lead to gap …

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 basic aspects of electrons in graphene (two-dimensional graphite) exposed to a strong
perpendicular magnetic field are reviewed. One of its most salient features is the relativistic …

A bstract We perform a bootstrap analysis of a mixed system of four-point functions of
bosonic and fermionic operators in parity-preserving 3d CFTs with O (N) global symmetry …

Artificial honeycomb lattices offer a tunable platform for studying massless Dirac
quasiparticles and their topological and correlated phases. Here we review recent progress …

In numerical simulations, spontaneously broken symmetry is often detected by computing
two-point correlation functions of the appropriate local order parameter. This approach …

The metal-insulator transition has been a subject of intense research since Mott first
proposed that the metallic behavior of interacting electrons could turn to an insulating one as …

We study the chiral Ising, the chiral XY, and the chiral Heisenberg models at four-loop order
with the perturbative renormalization group in 4-ε dimensions and compute critical …
