Light signature algorithm offers precise insight on viral proteins, brain disease markers and semiconductors

Researchers at Rice University have developed a new machine learning (ML) algorithm that excels at interpreting the “light signatures” (optical spectra) of molecules, materials and disease biomarkers, potentially enabling faster and more precise medical diagnoses and sample analysis.

Compact optical clock uses quantum interference for improved frequency stability

An atomic clock research team from the National Time Service Center of the Chinese Academy of Sciences has proposed and implemented a compact optical clock based on quantum interference enhanced absorption spectroscopy, which is expected to play an important role in micro-positioning, navigation, timing (μPNT) and other systems.

Using ‘shallow shadows’ to uncover quantum properties

It would be difficult to understand the inner workings of a complex machine without ever opening it up, but this is the challenge scientists face when exploring quantum systems. Traditional methods of looking into these systems often require immense resources, making them impractical for large-scale applications.

First observation of non-reciprocal Coulomb drag in Chern insulators reported

He Qinglin’s group at the Center for Quantum Materials Science, School of Physics, has reported the first observation of non-reciprocal Coulomb drag in Chern insulators. This breakthrough opens new pathways for exploring Coulomb interactions in magnetic topological systems and enhances our understanding of quantum states in such materials. The work was published in Nature Communications. […]

Physicists test quantum theory with atomic nuclei from a nuclear reaction

Many atomic nuclei have a magnetic field similar to that of Earth. However, directly at the surface of a heavy nucleus such as lead or bismuth, it is trillions of times stronger than Earth’s field and more comparable to that of a neutron star. Whether we understand the behavior of an electron in such strong […]

The first experimental observation of Dirac exceptional points

Exceptional points (EPs) are unique types of energy-level degeneracies that occur in non-Hermitian systems. Since their existence was first proposed more than a century ago, physicists have only been able to experimentally observe two types of EPs, both of which were found to give rise to exotic phases of matter in various materials, including Dirac […]

Ultrafast optical technique reveals how electrical double layers form in liquids

Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions from the liquid. This creates two distinct charged regions: the surface itself and a counter-charged region in the liquid: the so-called electrical double layer. While pivotal to energy storage devices, the speed of its formation has remained elusive.

Magnetic confinement advance promises 100 times more fusion power at half the cost

A team of fusion researchers at TAE Technologies, Inc., in the U.S., working with colleagues from the University of California, has developed a new type of fusion technology that the company claims produces 100 times the power of other designs while costing just half as much to run. Their study is published in the journal […]

Hey, what are these curved green flashes above my polymer semiconductor?

In every scientific discovery in the movies, a scientist observes something unexpected, scratches the side of his or her forehead and says “hmmmmm.” In just such a moment in real life, scientists from Canada observed unexpected flashes of curved green light from a red light-emitting polymer above its surface. The flashes were reminiscent of the […]

Observatory develops high-efficiency muon detection system with novel plastic scintillator design

Researchers from Sun Yat-sen University (SYSU) and the Institute of High Energy Physics (IHEP) have developed a novel top veto tracker system for the Taishan Antineutrino Observatory (TAO) experiment.

An earth-abundant mineral for sustainable spintronics

In 2023, EPFL researchers succeeded in sending and storing data using charge-free magnetic waves called spin waves, rather than traditional electron flows. The team from the Lab of Nanoscale Magnetic Materials and Magnonics, led by Dirk Grundler, in the School of Engineering, used radiofrequency signals to excite spin waves enough to reverse the magnetization state […]

Is our universe the ultimate computer?

Whether we are simply characters in an advanced virtual world is a much-debated theory, challenging previous thinking about the universe and our existence.
