Russian physicists have developed a method for drastically narrowing the emission spectrum of an ordinary diode laser, like that in a laser pointer. This makes their device a useful replacement for the more complex and expensive ...
In the last half-century, laser technology has grown into a multi-billion-dollar global industry and has been used in everything from optical-disk drives and barcode scanners to surgical and welding equipment.
Ultrashort optical pulses are becoming increasingly relevant in a number of applications, including distance measurement, molecular fingerprinting and ultrafast sampling. Many of these applications rely not only on a single ...
A team of researchers from MIT, the Max-Born-Institut, Technische Universität Berlin and Deutsches Elektronen-Synchrotron (DESY) has found that using ferrimagnets instead of ferromagnets could theoretically speed up spintronics ...
The interaction of traveling waves in dissipative systems, physical systems driven by energy dissipation, can yield unexpected and sometimes chaotic results. These waves, known as dissipative pulses (DSs), are driving experimental ...
Spacecraft outfitted with sails and propelled by the sun are no longer the stuff of science fiction or theoretical space missions. Now, a Rochester Institute of Technology researcher is taking solar sailing to the next level ...
Tiny magnetic vortex structures, so-called skyrmions, have been researched intensively for some time for future energy-efficient space-saving data storage devices. Scientists at Forschungszentrum Jülich have now discovered ...
Shamit Shrivastava, a post-doctoral researcher in the Department of Engineering Science, writes about a recent finding that has far-reaching consequences for the fundamental understanding of the physics of the brain. The ...
Imagine a metal bar that has been heated at one end. Instead of the heat gradually spreading over its entire length, the bar eventually becomes hot again at the place where it was originally. The fact that, paradoxically, ...
Researchers at the Department of Energy's Oak Ridge National Laboratory made the first observations of waves of atomic rearrangements, known as phasons, propagating supersonically through a vibrating crystal lattice—a discovery ...
