PPPL Physicist Uncovers Clues to Mechanism Behind Magnetic Reconnection

PPPL physicist Fatima Ebrahimi has published a paper showing that magnetic reconnection -- the process in which magnetic field lines snap together and release energy -- can be triggered by motion in nearby magnetic fields.

The Science of Consciousness, June 5-10, 2017

'The Science of Consciousness' ('TSC') is the world's largest and longest-running interdisciplinary conference on all aspects of the nature of conscious awareness, feelings and existence.

Zamolodchikov Invested as C.N. Yang Endowed Chair in Physics and Astronomy

Professor Alexander Zamolodchikov became the inaugural Chen Ning Yang - Wei Deng Endowed Chair in Physics and Astronomy on January 6 at an investiture ceremony in Beijing, China at the global headquarters of Bright Ocean's Corporation. A pioneer in modern theoretical physics and member of the National Academy of Sciences, Prof. Zamolodchikov is known internationally for his contributions to the study of condensed matter physics, conformal field theory and string theory. His impact on the field of physics can be measured by a simple metric: 18,000 -- the number of times his published research has been cited; one of the highest in physics to date.

Astronomers Find Seven Dwarf-Galaxy Groups, the Building Blocks of Massive Galaxies

A team of astronomers has discovered seven distinct groups of dwarf galaxies with just the right starting conditions to eventually merge and form larger galaxies, including spiral galaxies like the Milky Way.

Kawtar Hafidi Named Director of Physics Division

Argonne associate chief scientist Kawtar Hafidi has been named Argonne National Laboratory's next physics division director.

Melting Solid Below the Freezing Point

Phase transitions surround us--for instance, liquid water changes to ice when frozen and to steam when boiled. Now, researchers at the Carnegie Institution for Science* have discovered a new phenomenon of so-called metastability in a liquid phase. A metastable liquid is not quite stable. This state is common in supercooled liquids, which are liquids that cool below the freezing point without turning into a solid or a crystal. Now, scientists report the first experimental evidence of creating a metastable liquid directly by the opposite approach: melting a high-pressure solid crystal of the metal bismuth via a decompression process below its melting point.

Neutrons and a 'Bit of Gold' Uncover New Type of Quantum Phase Transition

In a paper published in Physical Review Letters, a team of researchers led by the Department of Energy's Oak Ridge National Laboratory reports the discovery of a new type of quantum phase transition. This unique transition happens at an elastic quantum critical point, or QCP, where the phase transition isn't driven by thermal energy but instead by the quantum fluctuations of the atoms themselves.

A Quark Like No Other

A University of Iowa physicist is at the forefront of the search to confirm the existence of a particle believed to give mass to all matter. Her group helped build and operates a sub-detector to search for bottom quarks, which are thought to appear when a Higgs boson decays.

Brookhaven National Laboratory's Top-10 Science Successes of 2016

From advances in accelerators and experiments exploring the building blocks of matter and making medical isotopes to new revelations about superconductors, nanomaterials, and biofuels, 2016 was a year of accomplishment at the U.S. Department of Energy's Brookhaven National Laboratory. Here are our Top-10 highlights.

Researchers Turn to "Citizen Scientists" for Help Identifying Gravitational Waves

Dr. Tyson Littenberg, a research astrophysicist at NASA's Marshall Space Flight Center and an adjunct professor in the Department of Space Science at The University of Alabama in Huntsville (UAH), is among a team of researchers who have launched "Gravity Spy," a crowdsourcing platform that tasks volunteer citizen scientists with sifting through LIGO data and identifying "families" of glitches that can be sorted by machine-learning algorithms.

Shattering Protons in High-Energy Collisions Confirms Higgs Boson Production

At the world's most powerful particle physics accelerator, physicists confirmed the Higgs boson production rate. The results match our understanding of how the universe works and will help build the data sets to explore the particles' properties.

Berkelium's Unexpected Chemistry Has Been Captured

Berkelium was one of a few elements that had yet to be characterized in detail. Researchers structurally characterized it and revealed unexpected findings.

Theory Provides Roadmap in Quest for Quark Soup 'Critical Point'

Thanks to a new development in nuclear physics theory, scientists exploring expanding fireballs that mimic the early universe have new signs to look for as they map out the transition from primordial plasma to matter as we know it. The theory work, described in a paper recently published as an Editor's Suggestion in Physical Review Letters (PRL), identifies key patterns that would be proof of the existence of a so-called "critical point" in the transition among different phases of nuclear matter.

Physics Tradition Bridges Past with Future

Associate Professor of Physics Ed Pogozelski and his student bridge-building competition have come a long way since the spaghetti year of '97. That's when he used food as the construction material of choice after learning -- just two weeks ahead of time-- that the annual physics department event was among his responsibilities as a new adjunct.
