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.

Bismuth Electrons and Nuclei Work Together as Qubits in a Quantum Computer

New research has demonstrated a way to make bismuth electrons and nuclei work together as qubits in a quantum computer.

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.

Physicist Anton Zeilinger Named AAAS Fellow

The American Association for the Advancement of Science (AAAS) was founded in 1874 and is the world's largest general scientific society, and publisher of the journal "Science".

European Funding Agencies Establish New Consortium for Astroparticle Physics

European funding agencies for astroparticle physics celebrate today the successful work of the ASPERA European funded network and the launch of the newly founded APPEC, the Astroparticle Physics European Consortium.

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.

UB Department of Physics to Host HiggsFest

You might call the Higgs boson the media darling of particle physics.

UC Riverside Physicist Elected as an APS Fellow for Hadronic Matter Study

Two physicists at the University of California, Riverside — Richard Seto and Jing Shi — have been elected as fellows of the American Physical Society (APS). Only 250 researchers received the high honor this year.

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.

Astronomers Present New Findings on Merging Galaxy Cluster’s Dark Matter

Astronomers were puzzled earlier this year when NASA's Hubble Space Telescope spotted an overabundance of dark matter in the heart of the merging galaxy cluster Abell 520. This observation was surprising because dark matter and galaxies should be anchored together, even during a collision between galaxy clusters.

New Paradigm to Understand Earliest Eras of Universe

A new paradigm for understanding the earliest eras in the history of the universe has been developed by scientists at Penn State. Using techniques from an area of modern physics called loop quantum cosmology, developed at Penn State, the scientists now have extended analyses that include quantum physics farther back in time than ever before -- all the way to the beginning.

New Model Helps Predict Charged Particle Movement in Complex Media

Picture two charged particles in a vacuum. Thanks to laws of elementary electrostatics, we can easily calculate the force these particles exert upon one another, and therefore predict their movements.

NIST Study Provides New Insights into Quantum Electrodynamics Theory

A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest* that the most rigorous predictions based on the fundamental theory of electromagnetism—one of the four fundamental forces in the universe, and harnessed in all electronic devices—may not accurately account for the behavior of atoms in exotic, highly charged states.

NASA's Chandra Observatory Detects X-Ray Jet from a Supermassive Black Hole

A jet of X-rays from a supermassive black hole 12.4 billion light years from Earth has been detected by NASA's Chandra X-ray Observatory. This is the most distant X-ray jet ever observed and gives astronomers a glimpse into the explosive activity associated with the growth of supermassive black holes in the early universe.
