Tomorrow's nonvolatile memory devices "“ computer memory that can retain stored information even when not powered "“ will profoundly change electronics, and Cornell University researchers have discovered a new way of measuring and optimizing their performance. Using a very fast oscilloscope, researchers led by Dan Ralph, the Horace White Professor of Physics, and Robert Buhrman, the J.E. Sweet Professor of Applied and Engineering Physics, have figured out how to quantify the...

TAU uses quantum mechanics to melt glass at Absolute ZeroQuantum mechanics, developed in the 1920s, has had an enormous impact in explaining how matter works. The elementary particles that make up different forms of matter "” such as electrons, protons, neutrons and photons "” are well understood within the model quantum physics provides. Even now, some 90 years later, new scientific principles in quantum physics are being described. The most recent gives the world a glimpse into...

Inspired by the popular confidence trick known as "shell game," researchers at UC Santa Barbara have demonstrated the ability to hide and shuffle "quantum-mechanical peas" "“"“ microwave single photons "“"“ under and between three microwave resonators, or "quantized shells." In a paper published in the Jan. 30 issue of the journal Nature Physics, UCSB researchers show the first demonstration of the coherent control of a multi-resonator architecture. This topic has been...

NASA's Time History of Events and Macroscale Interaction during Substorms (THEMIS) spacecraft combined with computer models have helped track the origin of the energetic particles in Earth's magnetic atmosphere that appear during a kind of space weather called a substorm. Understanding the source of such particles and how they are shuttled through Earth's atmosphere is crucial to better understanding the Sun's complex space weather system and thus protect satellites or even humans in space....

A new scientific discovery could have profound implications for nanoelectronic components.  Researchers from the Nano-Science Center at the Niels Bohr Institute, University of Copenhagen, in collaboration with Japanese researchers, have shown how electrons on thin tubes of graphite exhibit a unique interaction between their motion and their attached magnetic field "“ the so-called spin. The discovery paves the way for unprecedented control over the spin of electrons and may have a...

Electronics researchers love graphene. A two-dimensional sheet of carbon one atom thick, graphene is like a superhighway for electrons, which rocket through the material with 100 times the mobility they have in silicon. But creating graphene-based devices will be challenging, say researchers at the National Institute of Standards and Technology (NIST), because new measurements show that layering graphene on a substrate transforms its bustling speedway into steep hills and valleys that make it...

US-European team revisits 30-year-old breakthrough with new methods, understanding European and U.S. physicists this week are offering up the strongest evidence yet that magnetism is the driving force behind unconventional superconductivity. The findings by researchers from Rice University, the Max Planck Institute for Chemical Physics of Solids (MPI-CPfS) in Dresden, Germany, and other institutions were published online today in Nature Physics. The findings follow more than three decades of...

Glass is something we all know about. It's what we sip our drinks from, what we look out of to see what the weather is like before going outside and it is the backbone to our high speed communications infrastructure (optical fibers). But what most people don't know is that "glass transitions," where changes in structure of a substance accompanying temperature change get "frozen in," can show up during cooling of most any material, liquids through metals. This produces "glassy states," of that...

Ultra-short X-ray beams produced at the University of Michigan could one day serve as more sensitive medical diagnostic tools, and they could work like strobe lights to allow researchers to observe chemical reactions that happen in quadrillionths of a second. The researchers used the HERCULES high-intensity, table-top laser to create X-ray beams that rival those made in expensive and massive synchrotron particle accelerators. The National Synchrotron Light Source II, for example, under...

By Robert Sanders, UC Berkeley University of California, Berkeley, scientists have found a way to overcome one of the main limitations of ultrasound imaging "“ the poor resolution of the picture. Everyone who has had an ultrasound, including most pregnant women, is familiar with the impressionistic nature of the images. One of the limits to the detail obtainable with sonography is the frequency of the sound. The basic laws of physics dictate that the smallest objects you can "see" are...
