Controlling quantum particle states through structural phase transition of crystals

A research team has successfully fine-tuned the Rabi oscillation of polaritons, quantum composite particles, by leveraging changes in electrical properties induced by crystal structure transformation. Published in Advanced Science, this study demonstrates that the properties of quantum particles can be controlled without the need for complex external devices, which is expected to greatly enhance the feasibility of practical quantum technology. The team was led by Professor Chang-Hee Cho from the Department of Physics and Chemistry at DGIST.

Scientists source solar emissions with largest-ever concentration of rare helium isotope

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the sun. A Southwest Research Institute-led team of scientists sought the source of this unusual occurrence to better understand the mechanisms that drive solar energetic particles (SEPs) that permeate our solar system. SEPs are high-energy, accelerated particles including protons, electrons and heavy ions associated with solar events like flares and coronal mass ejections.

Hubble unveils first images of ongoing star cluster mergers near center of dwarf galaxies

A new study reports the first direct observation of merging star clusters in the nuclear region of dwarf galaxies. This detection confirms the feasibility of this formation route for nuclei in dwarf galaxies, which has long been debated. The study was published in Nature, and led by Postdoctoral Researcher Mélina Poulain from the University of Oulu, Finland.

Where to find the next Earth: Machine learning accelerates the search for habitable planets

A team from the University of Bern and the National Center of Competence in Research (NCCR) PlanetS has developed a machine-learning model that predicts potential planetary systems with Earth-like planets. The model could significantly accelerate and thus revolutionize the future search for habitable planets in the universe.

Hubble studies a nearby galaxy’s star formation

This NASA/ESA Hubble Space Telescope image features the picturesque spiral galaxy NGC 4941, which lies about 67 million light-years from Earth in the constellation Virgo (The Maiden). Because this galaxy is nearby, cosmically speaking, Hubble’s keen instruments are able to pick out exquisite details such as individual star clusters and filamentary clouds of gas and dust.

JWST observations detect dusty disk around the central star of Ring Nebula

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a planetary nebula designated Messier 57 (also known as NGC 6720), dubbed the Ring Nebula. As a result, they found that the central star of this nebula is surrounded by a dusty ring. The finding was detailed in a paper published April 1 on the arXiv preprint server.

Study unveils contributions to superconductivity in the vortex lattice structure of 2H-NbSe₂

Superconductivity is a quantum property of materials entailing an electrical resistance of zero at very low temperatures. In some materials, multiple electronic bands are known to contribute to the emergence of superconductivity, leading to multiple superconducting energy gaps. This phenomenon is referred to as multiband superconductivity.
