Turning off the superconductivity in a cuprate superconductor with light or magnetism produces a normal state with very similar fundamental physics.

A complex electrical ‘vortex’-like pattern discovered in ferroelectric materials mirrors a magnetic counterpart in ferromagnetic materials.

Researchers have developed a composite material that can morph into a new shape, hold that shape and then return to its original shape.

Researchers have cast doubt on an experimental approach for demonstrating the existence of axionic behavior in a Weyl semimetal.

Physicists have shown that fluctuations in tiny magnetic anomalies in 2D materials known as skyrmions can be used to generate random numbers.

Using just a small voltage and a magnet, researchers have manipulated a liquid metal, getting it to move and form shapes, without any form of contact.

Using a novel computational optimizer, researchers have designed a metamaterial for the asymmetric transmission of linearly polarized light.

Researchers have produced an electrochemical random access memory component with a 2D material, for use in computers that mimic the human brain.

Researchers have confirmed that cuprates make the transition to a superconducting state in two distinct steps at very different temperatures.
