A new approach that uses light to switch the magnetic states of a material could lead to faster, smaller and more energy-efficient data storage. Engineers at the University of California San Diego ...

Scientists have demonstrated a new method for generating and sustaining the high-quality electron beams required for X-ray lasers, a step toward making the instruments smaller and more affordable. The ...

A magnetic bit normally changes state because a field pushes its orientation from one direction to another. UC San Diego researchers have shown that carefully engineered light can perform that job ...

Using a specially engineered beam of light from an ultrafast laser, UC San Diego engineers demonstrate a new approach to ...
