Physicists have made one of the highest performance atomic clocks ever. ­­ Their instrument, known as an optical lattice atomic clock, can measure differences in time to a precision equivalent to losing just one second every 300 billion years and is the first example of a 'multiplexed' optical clock, where six separate clocks can exist in the same environment. Its design allows the team to test ways to search for…

The energy transport between atoms and molecules is the basis of all life. Such transport is based on interatomic forces known as the dipole-dipole interaction. Prof. Dr. Herwig Ott's research group at Technische Universität Kaiserslautern (TUK) has now succeeded in reproducing such a transport mechanism in a disordered system. For this purpose, the researchers experimentally observed the quantum mechanical…

Scientists at Brookhaven National Laboratory have used two-dimensional condensed matter physics to understand the quark interactions in neutron stars, simplifying the study of these densest cosmic entities. This work helps to describe low-energy excitations in dense nuclear matter and could unveil n

New Insights on the Interplay of Electromagnetism and the Weak Nuclear Force Nuclear theorists have discovered a major effect in neutron decay related to weak and electromagnetic forces interaction. This finding alters our understanding of neutron decay and signals the need for high-precision compu

Scientists have successfully detected the X-ray signature of a single atom for the first time. Using a pioneering technique known as synchrotron X-ray scanning tunneling microscopy (SX-STM), the team was able to identify and characterize individual atoms, opening new possibilities in environmental,

Pierre Agostini, Ferenc Krausz and Anne L'Huillier received the 2023 Nobel Prize in Physics for using attosecond-scale pulses of light to study the motions of electrons

Pierre Agostini, Ferenc Krausz, and Anne L'Huillier split the award for their ability to picture nature in a billionth of a billionth of a second

Nuclear physicists have made the most neutron-rich form of sodium yet, which will help reveal more about the complex world of nuclei. Physicists at RIKEN have created an exceptionally neutron-rich sodium isotope, 39Na, which was previously believed to be impossible. This breakthrough has major im

Study by the University of Bonn and the TU Darmstadt suggests errors in the interpretation of older measurements. A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some

Even though the EPA says sampling work needed to plan West Lake Landfill's eventual cleanup has now been completed, significant questions remain unanswered.

Utilizing ultra-high-precision laser spectroscopy on a simple molecule, a team of physicists headed by Professor Stephan Schiller Ph.D. of Heinrich Heine University Düsseldorf (HHU) measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. In their paper publishe

Particle collisions offer a new way to study interactions of hyperon particles with ordinary nuclear building blocks, potentially giving insight into the properties of neutron stars. In a groundbreaking study, scientists at the RHIC observed the directed flow of hypernuclei during particle collis

New X-ray capability could find wide application in environmental and medical research, as well as the development of batteries and microelectronic devices. Scientists at Argonne National Laboratory and various universities have successfully used X-ray beams to analyze a single atom, marking a gr

The Rydberg state is prevalent across various physical mediums such as atoms, molecules, and solid materials. Rydberg excitons, which are highly energized, Coulomb-bound electron-hole pair states, were initially identified in the 1950s within the semiconductor material, Cu2O. In a study published

UChicago researchers hope "islands" of exciton condensation could pave the way for new discoveries. Inside a lab, scientists marvel at a strange state that forms when they cool down atoms to nearly absolute zero. Meanwhile, just outside their window, trees are absorbing sunlight and converting it

The escalating risks of Russia's war in Ukraine have led scientists to study the unthinkable and model the aftermath of nuclear detonation.

MIT physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate — a key building block for a new type of quantum computer.

The legislation will be the subject of a hearing on March 7.
