Toward super-fast motion of vortices in superconductors

An international team of scientists from Austria, Germany, and Ukraine has found a new superconducting system in which magnetic flux quanta can move at velocities of 10 to 15 km/s. This opens access to investigations of the ...

How to get rid of the coffee-stain effect

The coffee-stain effect is a well-known effect in physics and daily life in which a dark-colored edge remains when a fluid containing particles evaporates. This is caused by an "avalanche" of particles moving to the outer ...

Toward lasers powerful enough to investigate a new kind of physics

In a paper that made the cover of the journal Applied Physics Letters, an international team of researchers has demonstrated an innovative technique for increasing the intensity of lasers. This approach, based on the compression ...

New method measures temperature within 3-D objects

University of Wisconsin-Madison engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in ...

Looping X-rays to produce higher quality laser pulses

Ever since 1960, when Theodore Maiman built the world's first infrared laser, physicists dreamed of producing X-ray laser pulses that are capable of probing the ultrashort and ultrafast scales of atoms and molecules.
