Novel Diffraction Spectrometer May Help Elucidate Quantum Mechanical Structure of Matter

Every photon in a laser beam marches in lockstep, at an identical wavelength that depends on what the laser is used for – for example, infrared lasers that drive the optic fiber internet. For many applications, lasers need to be precisely tuned to those wavelengths, and the wavelength-measuring instruments can be more expensive than the lasers themselves.

Charged Quasi-Particles Can be Manipulated for Applications in Optoelectronics and Valleytronics

When the dry lubricant, molybdenum disulfide, is stripped down to a single layer of atoms, a tightly bound quasi-particle comprised of two electrons and a hole forms with unique spin and valley properties, researchers from Case Western Reserve University and colleagues discovered.

Researchers Measure Temporal Profile of Free-Electron Laser X-ray Pulses with Femtosecond Precision

With their ultra short X-ray flashes, free-electron lasers offer the opportunity to film atoms in motion in complicated molecules and in the course of chemical reactions. However, for monitoring this motion, the arrival time and the temporal profile of the pulses which periodically illuminate the system, must be precisely known.

Study Results Provide New Insights into Planet Evolution

Rocky planets are thought to form through the random collision and sticking together of what are initially microscopic particles in the disc of material around a star.

Review Paper Covers New Theoretical Measures of Quantumness

Even before the article "The classical-quantum boundary for correlations: Discord and related measures" was published in Reviews of Modern Physics on 26 November, it had been cited nearly 100 times.

Unusually Massive Black Hole Challenges Current Galaxy Evolution Models

A group headed by Remco van den Bosch from the Max Planck Institute for Astronomy has discovered a black hole that shakes the foundations of current models of galaxy evolution. This monster has 17 billion solar masses and is thus significantly heavier than the models predict. And even more significantly: the object could be the most massive black hole known to date.
