New Theory to Avoid and Reverse Heating Effect in Quantum Cascade Lasers

Since its invention 50 years ago, laser light has conquered our daily life. Lasers of varying wave lengths and power are used in many parts of our life, from consumer electronics to telecommunication and medicine. However, not all wave lengths have been equally well researched.

Meson Decay Demonstrates Time Flows in Preferred Direction

Bending light around corners is usually done with mirrors, but now scientists have realized self-bending light beams that propagate along curved paths.

X-ray Laser Pulses Can Strip Electrons from Atoms to Create Ions with Strong Charges

Researchers using the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have found a way to strip most of the electrons from xenon atoms, creating a "supercharged," strongly positive state at energies previously thought too low.

Tetrapod Quantum Dots with Higher Brightness Improve Biochemical Assays

Millions of laboratory tests and biological assays are conducted every year to explore cellular processes. Quantum Materials Corporation has now developed tetrapod quantum dots, improved fluorescent markers that can more effectively gain knowledge of how body systems function and chronic conditions and diseases such as cancer metabolize and impact health and longevity.

Quark Gluon Plasma Emits Ultra Short Laser Pulses

Heavy ion collisions at CERN should be able to produce the shortest light pulses ever created. This was demonstrated by computer simulations at the Vienna University of Technology. The pulses are so short that they cannot even be measured by today's technological equipment. Now, a method has been proposed to create the world's most precise stopwatch for the world's shortest light pulses, using a detector which is going to be installed at CERN in 2018.

Researchers Amplify Noisy Quantum State of Single Photon without Adding Noise

Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise.

Quasars Probe Dark Energy

BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role of dark energy in the evolution of the universe. BOSS is the largest program of the third Sloan Digital Sky Survey (SDSS-III) and has just announced the first major result of a new mapping technique, based on the spectra of over 48,000 quasars with redshifts up to 3.5, meaning that light left these active galaxies up to 11.5 billion years in the past.

CdSe Quantum Dots and Nickel Catalysts Improve Light-Driven Hydrogen-Production Systems

Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is adding to its appeal by increasing the output and lowering the cost of current light-driven hydrogen-production systems.

Gold Nanospheres Generate a Quantum Kiss

Researchers from the Donostia International Physics Center (DIPC) and the Materials Physics Center in Donostia-San Sebastián (CFM) have observed for the first time, with optical methods, the quantum regime in the interaction between nano-sized spheres of gold. This quantum regime has been identified thanks to the change of colour of the gap or empty space between these particles when they are at distances of less than one nanometre. This work, published in Nature journal, enables literally “seeing” a quantum kiss between nanoparticles.

Quantum Weirdness Observed in Computer Chip Nanoelectronics

To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter.
