Acoustic experiments confirm topology can persist at gapless critical points

Two studies on critical topology have recently been published in the journal Nature. These studies were led by the teams of Prof. Baile Zhang at Nanyang Technological University, Singapore, and Prof. Jianhua Jiang at the University of Science and Technology of China, respectively. Prof. Xue-Jia Yu from the School of Physics at the Eastern Institute of Technology, Ningbo (EIT), served as a co-corresponding author on both papers and provided key theoretical guidance in the related experimental collaborations.

Radio galaxy from 12.5 billion years ago may be most powerful ever found

Astronomers have confirmed a powerful radio galaxy from nearly 12.5 billion years ago. The source, TXS 2354+015, was originally identified as a high-redshift candidate from its characteristic drop in optical light, and follow-up spectroscopy placed it at a redshift of 4.946. Their paper was posted to the arXiv preprint server on Sept. 23.

First observation of quantum spins shifting a centimeter-scale object in the lab

Modern technological breakthroughs like lasers, MRI scanners, semiconductors and quantum computers rest on the study of quantum mechanics. However, the field has predominantly focused on (sub)atomic phenomena far removed from our human senses.

One quantum material, two superconducting states: Stretching helps explain conflicting experiments

Unconventional superconductors can host unusual electronic states, but understanding what drives their superconductivity becomes difficult when different forms of order coexist. The kagome metal CsV3Sb5 has become a particularly debated example.

Levitating glass sphere becomes entangled with light at room temperature

Today, many physicists are actively exploring how light could be used to link objects through quantum entanglement. By fully harnessing the effect, they hope to unlock a wide array of applications, from secure communication networks spanning vast distances to sensitive new tests of the fundamental laws of physics.

Mars’ oddest cloud may be even odder than previously thought

Scientists using the European Space Agency’s Mars Express, in combination with a state-of-the-art meteorological model of the Red Planet, have found that there may be some exotic physics behind Mars’ most curious cloud. The paper, “Homogeneous ice Nucleation from Water Vapour Suggested by Elongated Clouds on Mars,” is published in Nature Geoscience.

Alcohol in space: Exotic methanol discovered in planet-building zones

An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory is a partner (NSF NRAO), has combined expertise from across the globe to open a new window on how the organic molecules that seed planets, and potentially life, form in space.

The first stand-alone nuclear clock is ticking in Vienna

For decades, researchers around the world have been working toward this goal—and now major advances are following in rapid succession. Vienna is now home to the world’s first nuclear clock that stabilizes itself, as atomic clocks typically do. This system has been shown to remain stable for more than 24 hours without intervention, and the related findings are published in the journal Nature.

Quantum computing shortcut makes particle collisions easier to simulate

Collisions between particles at high energies can sometimes produce new particles and shed light on interactions between the fundamental constituents of matter. Simulating these collisions and their underlying processes could yield valuable insights into how matter behaves at extremely small scales.

Computer scientist tracks satellites with automated observatory built from off-the-shelf technology

Allen Schnibben’s interest in space started when he was a child. “I picked up some books about the solar system when I was in elementary school. In middle school, I got a telescope and I started observing the night sky as a hobby,” said Schnibben, a computer scientist at Sandia National Laboratories. “My entire life, I’ve had an interest in space.” Now, Schnibben collects data on satellites at Sandia’s SOHBRIT facility, a 12-foot-wide (3.7-meter-wide) observatory.
