A UT physicist has been instrumental in the discovery of four new super-heavy chemical elements—atomic numbers 113, 115, 117, and 118—recently added to the periodic table. Robert Grzywacz, along with collaborators at Oak Ridge National Laboratory, developed the software used in the equipment that detects the new elements and helps analyze data from the experiments.

When UT’s physicists got involved in neutrino physics by joining the KamLAND (Kamioka Liquid Scintillator Anti-Neutrino Detector) experiment in 1997, they weren’t looking for financial gain. Yet with the experiment’s recent selection for the Breakthrough Awards Fundamental Physics prize, their efforts will, quite literally, pay off.
An international team led by joint UT-Oak Ridge National Laboratory faculty used America’s most powerful supercomputer, Titan, to calculate the neutron distribution and related observables of calcium-48, an isotope with an atomic nucleus consisting of twenty protons and twenty-eight neutrons. Computing the nucleus revealed that the difference between the radii of neutron and proton distributions—called the “neutron skin”—is considerably smaller than previously thought.
The Society of Physics Students dropped pumpkins frozen with liquid nitrogen from a height of 80 feet Friday near the Humanities and Social Sciences building as part of some Halloween fun. The event focused on science engagement and literacy. Several local media outlets covered the story.
Three UT physicists are drawing on their expertise in quantum mechanics to help solve a twenty-first century problem: keeping digital information safe at sea.
WBIR Channel 10 interviewed UT’s Paul Lewis about the recent rare supermoon eclipse, the first of four total lunar eclipses in this hemisphere.
Single atoms or molecules imprisoned by laser light in a doughnut-shaped metal cage could unlock the key to advanced storage devices, computers and high-resolution instruments, according to a recent UT-ORNL study. In a paper published in Physical Review A, a team composed of Ali Passian of Oak Ridge National Laboratory, and Marouane Salhi and George
Joint UT-ORNL professor Ali Passian helped develop the Hybrid Photonic Mode-Synthesizing Atomic Force Microscope.
Space.com recently featured graduate student Michael Sandoval in this story. He and a colleague found what appear to be the densest galaxies ever seen–cosmic realms where the night sky would appear ablaze with stars from the surface of a planet. The duo discovered ultracompact dwarf galaxies while looking through archives of astronomy observations by several different observatories. They conducted the
Paul Lewis, director of UT’s planetarium and space science outreach, will lead an exploration of the blue moon–the second full moon in a calendar month–later this week. Lewis, along with rangers from the Big South Fork National River and Recreation Area will celebrate this occurrence during an 8:00 p.m. program July 31 at the Bandy Creek Visitor Center.
