The potential discovery of anyons in a fractional quantum Hall device tests the limits of what is known about particles confined to two dimensions.

24.

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

25.

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

26.

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

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.

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