A key problem in the field of quantum criticality is to understand the nature of quantum phase
transitions in systems of interacting itinerant fermions, motivated by experiments on a variety …

Using holographic duality, we present an analytically controlled theory of quantum critical
points without quasiparticles, at finite disorder and finite charge density. These fixed points …

Recent experiments in graphene heterostructures have observed Chern insulators—integer
and fractional quantum Hall states made possible by a periodic substrate potential. Here, we …

Recently, two-dimensional Dirac materials patterned with a superlattice structure have
emerged as a rich platform for exploring correlated and topological quantum matter. In this …

Motivated by the appearance of a “reflection symmetry” in transport experiments and the
absence of statistical periodicity in relativistic quantum field theories, we propose a series of …

Quantum electrodynamics in 2+ 1 dimensions (QED 3) is a strongly coupled conformal field
theory (CFT) of a U (1) gauge field coupled to 2 N two-component massless fermions. The …

In nodal-line semimetals, Coulomb interactions and short-range correlated disorder are both
marginal perturbations to the clean noninteracting Hamiltonian. We analyze their interplay …

We calculate the zero-temperature dc electrical conductivity in the collisionless ℏ ω/k BT→∞
limit at superconductor-insulator transitions in the (2+ 1) d XY model universality class. We …

The anomalous Hall effect (AHE) is highly sensitive to disorder in the metallic phase. Here
we show that statistical correlations between the charge-spin disorder sectors strongly affect …

The interplay of interactions and disorder in two-dimensional (2D) electron systems has
actively been studied for decades. The paradigmatic approach involves starting with a clean …
