Stacked up against the rest: 2D nano-semiconductors advancing quantum technology

Quantum technology is quantifiable in qubits, which are the most basic unit of data in quantum computers. The operation of qubits is affected by the quantum coherence time required to maintain a quantum wave state.

Is the shallow pool in Paris really slowing Olympic swimmers down? Here’s what the science says

There has been plenty of rain, sweat and tears shed at the Paris Olympics this week. But the pool at the heart of La Defénce Arena has suffered a drought of world records that has athletes and officials scratching their heads.

Microscopy breakthrough promises better imaging for sensitive materials

An international team of scientists, led by Trinity College Dublin, has devised an innovative imaging method using state-of-the-art microscopes that significantly reduces the time and radiation required. Their work represents a significant breakthrough that will benefit several disciplines, from materials science to medicine, as the method promises to deliver improved imaging for sensitive materials such […]

Nuclear physicists question origin of radioactive beryllium in the solar system

Scientists have determined that a rare element found in some of the oldest solids in the solar system, such as meteorites, and previously thought to have been forged in supernova explosions, actually predate such cosmic events, challenging long-held theories about its origin.

New technique measures superconductivity at very high pressures

In 1911, Heike Kamerlingh Onnes discovered the first superconductor, metallic mercury when cooled to a critical temperature of 4.2 Kelvin, where it conducts electricity without resistance. Ever since materials scientists have been on a quest to better understand the phenomenon and whether other elements and materials have higher critical temperatures that could make them useful […]

A new technique to calculate the physical running of couplings in quadratic gravity

Researchers at the International School for Advanced Studies in Trieste, University of Massachusetts, and Instituto de Física Teórica at Universidade Estadual Paulista in Brazil recently introduced an alternative approach to derive the correct physical beta functions of couplings in quadratic gravity. Their paper, published in Physical Review Letters, could contribute to the use of the […]

Cryomodule assembly technicians rev up Jefferson Lab’s electron-beam racetrack

At the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility, the underground Continuous Electron Beam Accelerator Facility (CEBAF) more closely resembles a racetrack than it does a racecar. As a DOE Office of Science user facility, CEBAF includes a particle accelerator that enables the research of more than 1,900 nuclear physicists worldwide.

Researchers develop general framework for designing quantum sensors

Researchers from North Carolina State University and the Massachusetts Institute of Technology have designed a protocol for harnessing the power of quantum sensors. The protocol could give sensor designers the ability to fine-tune quantum systems to sense signals of interest, creating sensors that are vastly more sensitive than traditional sensors.

Ce-doped yttria transparent ceramic: A new ultraviolet-shielding material for extreme conditions

Ultraviolet (UV) radiation can break most of the chemical bonds in organic matter, and prolonged exposure to ultraviolet light can cause significant harm to humans and objects. In response, UV-shielding materials have been developed to fulfill various commercial requirements, including UV-shielding windows, food containers, contact lenses, and masks.

A modified model designed to simulate nuclear fission sheds light on how rumors start, spread, and end

It has never been easier to spread false or misleading information online. The anonymous, impersonal nature of the internet, combined with advanced tools like artificial intelligence, makes it trivial for bad actors to manipulate the truth and challenging for everyone else to separate reality from fiction. In this modern climate of disinformation, understanding how falsehoods […]

Engineers use machine learning to measure chaos in systems

How do we measure chaos and why would we want to? Together, Penn engineers Dani S. Bassett, J. Peter Skirkanich Professor in Bioengineering and in Electrical and Systems Engineering, and postdoctoral researcher Kieran Murphy leverage the power of machine learning to better understand chaotic systems, opening doors for new information analyses in both theoretical modeling […]

The major Atlantic current that keeps Northern Europe warm could have new variations and tipping points

Northern Europe is relatively warm given its place on the globe. For example, although north of most major Canadian cities, London is warmer than all of them (even Vancouver in British Columbia). But this warmth could disappear by the turn of the century thanks to global warming.

Optimization algorithm successfully computes the ground state of interacting quantum matter

Over the past decades, computer scientists have developed various computing tools that could help to solve challenges in quantum physics. These include large-scale deep neural networks that can be trained to predict the ground states of quantum systems. This method is now referred to as neural quantum states (NQSs).

Save your data on printable magnetic devices? New laser technique’s twist might make this reality

The proliferation of all things digital doesn’t mean that printing technology is no longer relevant. In fact, printing technology is required to make the semiconductors necessary for the digital world. And as an Osaka Metropolitan University-led team has shown using a new printing technique, printable magnetic devices for high-density data storage might soon be realized. […]
