Relativistic effects on long-range interactions between objects

A team led by researchers María José Caturla and Carlos Untiedt, from the University of Alicante Department of Applied Physics, have studied the importance of relativistic effects on long-range interactions between objects. ...

New quantum materials offer novel route to 3-D electronic devices

Researchers have shown how the principles of general relativity open the door to novel electronic applications such as a three-dimensional electron lens and electronic invisibility devices. In a new study funded by the Academy ...

Friction in the vacuum?

(Phys.org)—When three physicists first discovered through their calculations that a decaying atom moving through the vacuum experiences a friction-like force, they were highly suspicious. The results seemed to go against ...

The universe, where space-time becomes discrete

In quantum gravity, classical physics and quantum mechanics are at odds: scientists are still uncertain how to reconcile the quantum "granularity" of space-time at the Planck scale with the theory of special relativity. In ...
