Despite their immense promise to solve new kinds of problems, today's quantum computers are inherently prone to error. A small perturbation in their surrounding environment— a change in temperature, pressure, or magnetic ...

Fast radio bursts—intense, milliseconds-long flashes of radio energy from outer space—have puzzled astronomers since they were first spotted in 2007. A single burst can emit as much energy in its brief life as the Sun ...

Gravitational wave astronomy is still in its early stages. So far it has focused on the most energetic and distinct sources of gravitational waves, such as the cataclysmic mergers of black holes and neutron stars. But that ...

Perturbing electron spins in a magnet usually results in excitations called "spin waves" that ripple through the magnet like waves on a pond that's been struck by a pebble. In a new study, Rice University physicists and their ...

Earth's magnetic field does more than keep everyone's compass needles pointed in the same direction. It also helps preserve Earth's sliver of life-sustaining atmosphere by deflecting high energy particles and plasma regularly ...

On the largest scales, the universe is ordered into a web-like pattern: galaxies are pulled together into clusters, which are connected by filaments and separated by voids. These clusters and filaments contain dark matter, ...

On Oct. 5, 2020, the rapidly rotating corpse of a long-dead star about 30,000 light years from Earth changed speeds. In a cosmic instant, its spinning slowed. And a few days later, it abruptly started emitting radio waves.

Topological phases are not restricted to electronic systems. They can also occur in magnetic materials whose properties are described in terms of magnetic waves—or so-called magnons. However, even though scientists have ...
