Quantum information lost after a measurement can be recovered using quantum error correction methods.

Microparticles suspended in an optical cavity may be a new way to detect gravity waves.

Surface spectroscopy shows that a material long known as a Kondo insulator also exhibits the metallic surface states of a topological insulator.

According to new calculations, thin films of transition-metal oxides could be promising materials for high-efficiency solar cells.

A solid’s surface tension is usually difficult to separate from its bulk elasticity, but a new technique determines this property by measuring the contact angle of small droplets on a soft surface.

Complex networks of disk bearings rotating in unison have an easier time maintaining this synchronization when the mass and radius of each bearing obeys a simple relationship.
