Sensing and controlling microscopic spin density in materials

Electronic devices typically use the charge of electrons, but spin—their other degree of freedom—is starting to be exploited. Spin defects make crystalline materials highly useful for quantum-based devices such as ultrasensitive ...

Physicists discover a new switch for superconductivity

Under certain conditions—usually exceedingly cold ones—some materials shift their structure to unlock new, superconducting behavior. This structural shift is known as a "nematic transition," and physicists suspect that ...

Scientists map gusty winds in a far-off neutron star system

An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star like cotton candy as it pulls in material from a nearby star. As the disk spins, it whips up powerful winds that ...

Scientists boost quantum signals while reducing noise

A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer, which harnesses quantum mechanical phenomena to solve certain problems too complex ...
