Taking the ‘Random’ out of a Random Laser

Taking the ‘Random’ out of a Random Laser

Random Lasers are tiny structures emitting light irregularly into different directions. Scientists at the Vienna University of Technology have now shown that these exotic light sources can be accurately controlled.   The light they emit is as unique as a fingerprint: random lasers are tiny devices with a light emission pattern governed by random scattering […]

Cities Are a New Kind of Complex System: Part Social Reactor, Part Network

Cities Are a New Kind of Complex System: Part Social Reactor, Part Network

Cities have long been likened to organisms, ant colonies, and river networks. But these and other analogies fail to capture the essence of how cities really function.   New research by Santa Fe Institute Professor Luis Bettencourt suggests a city is something new in nature — a sort of social reactor that is part star […]

Quest for Quantum Computing Advanced

Research teams from UW-Milwaukee and the University of York investigating the properties of ultra-thin films of new materials are helping bring quantum computing one step closer to reality. An on-going collaboration between physicists from York and the University of Wisconsin, Milwaukee, USA, is focusing on understanding, tailoring and tuning the electronic properties of topological insulators […]

Heady Mathematics: Describing Popping Bubbles in a Foam

Heady Mathematics: Describing Popping Bubbles in a Foam

Bubble baths and soapy dishwater, the refreshing head on a beer and the luscious froth on a cappuccino. All are foams, beautiful yet ephemeral as the bubbles pop one by one.   Two University of California, Berkeley, researchers have now described mathematically the successive stages in the complex evolution and disappearance of foamy bubbles, a […]

Newly Observed Properties of Vacuums: Light Particles Illuminate the Vacuum

Newly Observed Properties of Vacuums: Light Particles Illuminate the Vacuum

In an article published in the Proceedings of the National Academy of Sciences, researchers from Aalto University and the VTT Technical Research Centre of Finland showed experimentally that vacuum has properties not previously observed. According to the laws of quantum mechanics, it is a state with abundant potentials. Vacuum contains momentarily appearing and disappearing virtual […]

Quantum Algorithm Breakthrough: Performs a True Calculation for the First Time

Quantum Algorithm Breakthrough: Performs a True Calculation for the First Time

An international research group led by scientists from the University of Bristol, UK, and the University of Queensland, Australia, has demonstrated a quantum algorithm that performs a true calculation for the first time. Quantum algorithms could one day enable the design of new materials, pharmaceuticals or clean energy devices.   The team implemented the ‘phase […]

New Material Interface Improves Functioning of Non-Silicon-Based Electronic Devices

New Material Interface Improves Functioning of Non-Silicon-Based Electronic Devices

For the first time, researchers have designed a special material interface that has been shown to add to and to improve the functioning of non-silicon-based electronic devices, such as those used in certain kinds of random access memory (RAM). According to Qi Li, a professor of physics at Penn State University and the leader of […]
