Scientists calculate predictions for meson measurements

Nuclear physics theorists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have demonstrated that complex calculations run on supercomputers can accurately predict the distribution of electric charges in mesons, particles made of a quark and an antiquark. Scientists are keen to learn more about mesons—and the whole class of particles made of quarks, […]

Experiment reveals how Earth’s magnetic field influences flow in planet’s core

A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs Magnétiques Intenses, in France, has demonstrated how Earth’s magnetic field may be influencing internal flow, using what they describe as a Little Earth Experiment.

Controlling skyrmions at room-temperature in 2D topological spin structure technology

The Korea Research Institute of Standards and Science (KRISS) has, for the first time in the world, generated and controlled skyrmions at room temperature in two-dimensional (2D) materials. This achievement reduces power consumption compared to traditional three-dimensional (3D) systems while maximizing quantum effects, making it a core technology for the development of room-temperature quantum computers […]

Scientists use high-energy heavy ion collisions as a new tool to reveal subtleties of nuclear structure

Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory—to reveal subtle details about the shapes of atomic nuclei.

Quantum vortices confirm superfluidity in supersolid

Supersolids are a new form of quantum matter that has only recently been demonstrated. The state of matter can be produced artificially in ultracold, dipolar quantum gases. A team led by Innsbruck physicist Francesca Ferlaino has now demonstrated a missing hallmark of superfluidity, namely the existence of quantized vortices as a system’s response to rotation. […]

Kagome superconductor breaks the rules at record-breaking temperatures

Using muon spin rotation at the Swiss Muon Source SmS, researchers at the Paul Scherrer Institute (PSI) have discovered that a quantum phenomenon known as time-reversal symmetry breaking occurs at the surface of the Kagome superconductor RbV3Sb5 at temperatures as high as 175 K. This sets a new record for the temperature at which time-reversal […]

Flow of the future: AI models tackle complex particle drag coefficients

Accurately modeling particle movement through fluids is crucial in fields ranging from chemical engineering to aerospace. The drag coefficient, which influences how particles settle and move in fluid environments, is a core factor in these calculations. While the behavior of spherical particles is well understood, predicting the drag coefficient of irregularly shaped particles has long […]

Bach, Mozart or jazz: Scientists provide a quantitative measure of variability in music pieces

Physicists at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) have investigated to which extent a piece of music can evoke expectations about its progression. They were able to determine differences in how far compositions of different composers can be anticipated. In total, the scientists quantitatively analyzed more than 550 pieces from classical and […]

Multicomponent hydride designs could advance science of superconducting materials

New materials designed by a University of Illinois Chicago graduate student may help scientists meet one of today’s biggest challenges: building superconductors that operate at normal temperatures and pressures.

Defibrillation devices can still save lives using 1,000 times less electricity, optimized model finds

In a paper published in Chaos, researchers from Sergio Arboleda University in Bogotá, Colombia, and the Georgia Institute of Technology in Atlanta used an electrophysiological computer model of the heart’s electrical circuits to examine the effect of the applied voltage field in multiple fibrillation-defibrillation scenarios. They discovered far less energy is needed than is currently […]

Study identifies promising materials for fusion reactors

Nuclear fusion could be an ideal solution to mankind’s energy problem, guaranteeing a virtually limitless source of power without greenhouse gas emissions. But there are still huge technological challenges to overcome before getting there, and some of them have to do with materials.

Theoretical framework could improve data gathering in biological systems

To effectively adapt to change, living organisms rely on their ability to rapidly detect and process sensory information in their surroundings. The sensory information available at a given time continuously changes, which means that it can typically only be observed partially and for a limited amount of time.
