Researchers control elusive spin fluctuations in 2-D magnets

Like Bigfoot and the Loch Ness monster, critical spin fluctuations in a magnetic system haven't been captured on film. Unlike the fabled creatures, these fluctuations—which are highly correlated electron spin patterns—do ...

Imaging magnetic instabilities using laser accelerated protons

The magnetic structures resulting from a plasma instability predicted by the physicist Erich Weibel about 50 years ago have been evidenced at surprisingly large scales in a laser-driven plasma in the prestigious journal Nature ...

Quantum transition makes electrons behave as if they lack spin

The common phase transitions are those that occur as a function of temperature variation. Ice changes phase to become liquid water at 0 degrees Celsius. Liquid water changes phase to become water vapor at 100 degrees Celsius. ...

Scientists explain the low-temperature anomaly in superconductors

An international group of scientists, including a researcher from Skoltech, has completed an experimental and theoretical study into the properties displayed by strongly disordered superconductors at very low temperatures. ...

Researchers validate several fluctuation theorems for first time

Researchers at Purdue University have performed the first experimental tests of several fundamental theorems in thermodynamics, verifying the relationship between them and providing a better understanding of how nanoparticles ...

New X-ray laser technique reveals magnetic skyrmion fluctuations

A new way of operating the powerful X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory has enabled researchers to detect and measure fluctuations in magnetic structures being considered for new ...
