Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have proposed a key indicator that may reveal the emergence of quark-gluon plasma (QGP) by analyzing particle “fingerprints” generated in heavy-ion collisions.

Published in Physics Letters B, the study provides a new perspective for exploring the evolution of matter in the .

About 13.8 billion years ago, within a millionth of a second after the Big Bang, the universe existed in an ultra-hot and dense state. Instead of protons and neutrons, the fundamental building blocks of matter were free quarks and gluons—a unique state known as QGP. As the universe expanded and cooled, the QGP gradually condensed into the we recognize today.

A team of infectious disease specialists and environmental engineers at Université Claude Bernard Lyon’s, École Centrale de Lyon, in France, and the University of Rome La Sapienza, in Italy, has found via experiments that the physical characteristics of exhaled droplets play a role in the transmission of infectious diseases.

In their study published in the journal Physical Review Fluids, the group asked volunteers to breathe normally while silent, to speak normally, and to cough, while their exhausted droplet characteristics were measured.

Prior research has shown that many are spread via tiny expelled through the nose and mouth of infected people as they breathe. These droplets are small enough to hang in the air long enough for others to inhale them, leading to infection. Prior research has also shown that some people can be characterized as superspreaders—for some reason, they infect more people than do others. Some suspect that this might be due to the size of droplets expelled by superspreaders or the distance the droplets travel once expelled.

A recent study found that the Hubbard model failed to accurately predict the behavior of a simplified one-dimensional cuprate system. According to scientists at SLAC, this suggests the model is unlikely to fully account for high-temperature superconductivity in two-dimensional cuprates.

Superconductivity, the phenomenon where certain materials can conduct electricity without any energy loss, holds great potential for revolutionary technologies, from ultra-efficient power grids to cutting-edge quantum devices.

A recent study published in Physical Review Letters.

A mysterious menagerie of quantum states — once purely theoretical — has been brought to life by researchers at Columbia using twisted molybdenum ditelluride.

These newly observed states, some never seen before, hint at the possibility of topological quantum computers that don’t require magnetic fields, overcoming a major obstacle in the field. By employing a highly sensitive optical technique, scientists have not only identified a range of exotic quantum states but also demonstrated a new experimental approach that may transform the way we study quantum matter.

Quantum States: A Growing “Zoo”

Working with the Quantum Statistical Physics (PQS) group, Dengis developed a protocol for rapidly generating NOON states. “These states, which look like miniature versions of Schrödinger’s famous cat, are quantum superpositions,” he explains. “They are of major interest for technologies such as ultra-precise quantum sensors or quantum computers.”

The obstacle of time

The main challenge? Manufacturing these states normally takes far too long. We’re talking tens of minutes or more, which often exceeds the lifetime of the experiment. The cause? An energy bottleneck, a “sharp bend” in the system’s evolution that forces it to slow down.

The Ripple cryptocurrency npm JavaScript library named xrpl.js has been compromised by unknown threat actors as part of a software supply chain attack designed to harvest and exfiltrate users’ private keys.

The malicious activity has been found to affect five different versions of the package: 4.2.1, 4.2.2, 4.2.3, 4.2.4, and 2.14.2. The issue has been addressed in versions 4.2.5 and 2.14.3.
