The combination of trivial and topological band insulators with a superconductor is bringing anyons—particles that behave neither according to purely Bose nor Fermi statistics—into the three-dimensional world.

New excited states have been observed in ${}^{212}\text{Po}$ that are associated with a configuration in which an alpha particle is combined with a doubly-magic ${}^{208}\text{Pb}$ core.

The signal-to-noise ratio for room-temperature readout of individual qubits can be substantially improved by taking an indirect route through intermediate energy levels.

With the right configuration of laser beams, researchers could measure how much of an ultracold atomic gas is actually superfluid.

A recent theory of high-energy bottom quark jet quenching in nuclear collisions accentuates the novelty of heavy quark jet dynamics in strongly coupled quark-gluon plasmas discovered at the Relativistic Heavy Ion Collider.

The energy-momentum relationship of electrons on the surface of an ideal topological insulator forms a cone, which, when warped, can lead to unusual phenomena such as enhanced interference around defects and a magnetically ordered exotic surface.

The STAR detector at RHIC has measured a signal that may indicate parity violation occurs in metastable regions of the superdense matter.

The magnetic state of a multiferroic device can be controlled purely by an electric field—a property that could greatly reduce overheating in data storage devices.

The insights of a provocative connection between general relativity and quantum field theory, called the AdS/CFT correspondence, have been extended to rotating black holes that can occur astrophysically.
