Controlling nickelate nano-switches with light

Dr. Giordano Mattoni, quantum researcher at TU Delft, and his collaborators have shown that the nano-electronic phase transition in a class of materials known as nickelates can be controlled by laser light. Their findings, ...

New method achieves 4D imaging of fluids in pores

A method based on CT (computed tomography)—a type of imaging that is widely used in hospitals—can help improve our understanding of CO2 storage, batteries, and processes in the body such as nutrient uptake.

Breaking metamaterial symmetry with reflected light

Optical activity—rotation of the polarization of light—is well known to occur within materials that differ from their mirror image. But what happens if this symmetry is broken by the direction of illumination rather than ...

Pavlov's classical conditioning inspires materials scientists

Researchers have successfully trained a material to respond to an originally neutral stimulus, a gel that can be taught to melt without needing heating. Their work, recently published in Nature Communications, was inspired ...

Scientists tap into AI to put a new spin on neutron experiments

Scientists seek to use quantum materials—those that have correlated order at the subatomic level—for electronic devices, quantum computers, and superconductors. Quantum materials owe many of their properties to the physics ...

Training data for autonomous driving

Autonomous cars must perceive their environment true to reality. The corresponding algorithms are trained using a large number of image and video recordings. For the algorithm to recognize single image elements, such as a ...
