Researchers investigate the potential of metal grids for future electronic components

Scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition, they have discovered that for every hole ("antidot"), three magnetic states can be configured in a nanometer-scale magnetic perforated grid. The results have been published in the journal Scientific Reports.

History’s First Science Experiments

In this Insight I’m going to talk about two of the first science experiments in recorded history. One was allegedly performed by the Prophet Elijah in Israel in the 800s BC, the other by the Pharaoh Psammetichus in Egypt in the 600s BC. In each case, we only have one primary source from long after […]

New device simplifies circuitry needed to sense temperature changes

Research pushes concept of entropy out of kilter

Entropy, the measure of disorder in a physical system, is something that physicists understand well when systems are at equilibrium, meaning there's no external force throwing things out of kilter. But new research by Brown University physicists takes the idea of entropy out of its equilibrium comfort zone.

Synopsis: Number of Cycles Matters for a Quantum Engine

Theoretical calculations show that the performance of a quantum heat engine over several cycles can’t be judged by analyzing just a single cycle. [Physics] Published Thu Feb 02, 2017

Experiment involving ultracold rubidium lifts off with research rocket

Physicists want to use ultracold gases in space to measure the Earth's gravitational field, to subject Einstein's Equivalence Principle to an accurate test, and also to detect gravitational waves. The first flight in a sounding rocket...Show More Summary

More efficient nano-LED opens door to faster microchips

The electronic data connections within and between microchips are increasingly becoming a bottleneck in the exponential growth of data traffic worldwide. Optical connections are the obvious successors but optical data transmission requires an adequate nanoscale light source, and this has been lacking. Show More Summary

Scientists have simplified the simulation of high-precision optical instruments

Physicists from MIPT and University Jean Monnet (France) have developed a new simulation method for optical elements used in many modern instruments and devices. Their paper, presenting a description of the method which enables complex optical devices to be designed on gaming graphics cards, has been published in the Journal of Quantitative Spectroscopy and Radiative Transfer.

Physicists realize exotic quantum system robust to mixing by periodic forces

A team of researchers led by LMU physics professor Immanuel Bloch has experimentally realized an exotic quantum system which is robust to mixing by periodic forces.

Physics Blogging Round-Up: January

It’s a new month now, so it’s time to share links to what I wrote for Forbes last month: — Small College Astronomers Predict Big Stellar Explosion: I mostly leave astronomy stories to others, but I heard about this from a friend at Calvin College, and it’s a story that hits a lot of my…

Deducing how dinosaurs moved

Matthew R Francis describes how physicists are modelling the movements of these ancient beasts

Quantum phase transition observed for the first time

A group of scientists led by Johannes Fink from the Institute of Science and Technology Austria (IST Austria) reported the first experimental observation of a first-order phase transition in a dissipative quantum system. Phase transitions include such phenomena as the freezing of water at the critical temperature of 0 degrees Celsius. Show More Summary

Researchers break data transfer efficiency record

Researchers at the Department of Energy's Oak Ridge National Laboratory have set a new record in the transfer of information via superdense coding, a process by which the properties of particles like photons, protons and electrons are used to store as much information as possible.
