The experimental realization of quantum degenerate cold Fermi gases with large hyperfine spins opens up a new opportunity for exotic many-body physics.

When electronic instabilities give rise to three coexisting density waves, interference between them may lock into a state with helicity.

Networks of photonic devices with broken time-reversal symmetry may provide a way to create a quantum simulator to study strongly correlated systems.

Although theoretical approaches to modeling “strange metals,” such as the cuprate superconductors, originate from apparently different sources, research now suggests they flow toward a single universal model.

Photoemission spectroscopy has identified a new topological insulator with nearly “ideal” surface states.

New theoretical work shows that in two-dimensional condensed matter systems, one-dimensional processes such as forward or backward scattering have a dramatic effect on the physical behavior of fermions near a quantum critical point and derail attempts to get an accurate description of a non-Fermi-liquid.

High-resolution angle-dependent quantum oscillations in underdoped cuprates and unrestricted fits are used to suggest a new Fermi surface topology.

Theory that takes into account the time-dependent nature of electronic transport through a quantum dot reveals fluctuations that could affect rapid switching of nanoscale electronic devices.

By doping the topological insulator Bi2Te3 with magnetic manganese, researchers have turned it into a dilute ferromagnetic semiconductor.

A fundamental theoretical technique for treating interacting fermions confined to one dimension is generalized to include systems out of equilibrium.

A new phase of coexisting superconductivity and magnetic order is discovered in CeCoIn5.

Unconventional superconductors in the proximity of a topological insulator exhibit zero-energy Majorana surface states.

Behavior particular to quantum critical metals is, surprisingly, found in a class of insulators.

Coupled atom cavities can emulate the many-body behavior of condensed matter systems.

Calculations reveal the effect of dimensionality in a prototypical charge-density-wave material.

A new method of thermometry for ultracold atoms in optical lattices has the potential to accurately measure temperatures down to $50\text{pK}$.

A new renormalization group approach that maps lattice problems to tensor networks may hold the key to solving seemingly intractable models of strongly correlated systems in any dimension.

An alternative approach in density-functional theory addresses the effects of strong correlations in many-particle quantum systems.

An angle-resolved photoemission spectroscopy study of electron transport along quasi-one-dimensional $\text{Mo}$-$\text{O}$ chains of ${\text{Li}}_{0.9}{\text{Mo}}_6{\text{O}}_{17}$ reveals puzzling behavior that does not fit within the available one-dimensional theory frameworks and likely points to undiscovered physics.

A theoretical framework to explain how a hole moves through an antiferromagnetically and orbitally ordered lattice could also provide insight into the interplay between these two ordered phases.
