Exchange bias in van der Waals heterostructures

This phenomenon has a number of applications in magnetic sensors and magnetic reading heads, which, however, have not been reported in van der Waals heterostructures before.

Electrons line dance in a superconductor

Scientists have confirmed a long-standing theoretical prediction for high-temperature superconductors. Different states of matter make superconductivity possible. One of those theorized states of matter is called a pair density wave. The scientists confirmed pair density waves using advanced microscopic imaging techniques.

Hammer-on technique for atomic vibrations in a crystal

Vibrations of atoms in a crystal of the semiconductor gallium arsenide are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial distribution of charge between gallium and arsenic atoms acts back on their motions via electric interactions.
