New stable quantum batteries can reliably store energy into electromagnetic fields

Two examples of “quantum phones”, both charged by quantum batteries based on electromagnetic fields. On the left, a charging protocol not using a micromaser approach leads to uncontrolled battery charging with possible damages. On the right, a charging protocol based on micromasers is able to self-control the amount of charge deposited into the quantum phone. … Read more

Researchers find new ways to steer fusion with lasers and magnetic fields

Assistant Professor Arijit Bose is a new member of the University of Delaware’s Department of Physics and Astronomy. He has a grant from the Sandia National Lab to study inertial confinement fusion which uses magnetized pressure to produce nuclear fusion. Credit: Jeffrey C.
