Physicists discover a new switch for superconductivity

Under certain conditions—usually exceedingly cold ones—some materials shift their structure to unlock new, superconducting behavior. This structural shift is known as a "nematic transition," and physicists suspect that ...

Superconductivity's third side unmasked

The debate over the mechanism that causes superconductivity in a class of materials called the pnictides has been settled by a research team from Japan and China. Superconductivity was discovered in the pnictides only recently, ...

Paper proposes method to create gravitational fields

Producing and detecting gravitational fields at will using magnetic fields, controlling them for study, working with them to produce new technologies—it sounds impossible, but Prof. André Füzfa of Namur University has ...

What happens when the poles flip?

Have you heard the startling news that the Earth's poles might flip? Perhaps in the response to a close pass from the mysterious Planet X? Are you imagining the entire Earth actually flipping over on its side or rotating ...

Bethe strings experimentally observed

Ninety years ago, the physicist Hans Bethe postulated that unusual patterns, so-called Bethe strings, appear in certain magnetic solids. Now, an international team has succeeded in experimentally detecting such Bethe strings ...
