Scientists have used laser-excited thorium-229 to develop a highly sensitive method for detecting ultralight dark matter, leveraging its unique nuclear transition to probe interactions with forces much weaker than gravity, opening new avenues in fundamental physics research.
An international research team has used laser spectroscopy to study fermium isotopes, providing insights into the nuclear structure of superheavy elements. Their findings, published in Nature, reveal that nuclear shell effects diminish as nuclear mass increases, with macroscopic properties becoming more dominant. This research enhances understanding of the stabilization processes in heavy elements and supports theoretical predictions about the reduced influence of local shell effects in heavier nuclei.
Physicists led by Professor Stephan Schiller have used ultra-high-precision laser spectroscopy to measure the wave-like vibration of atomic nuclei in simple molecules, confirming the established force between atomic nuclei and refining our understanding of quantum theory. The measurements offer the most precise confirmation to date of the wave-like movement of nuclear material and provide important tests for new physical effects related to Dark Matter. The researchers have not found evidence of any deviation from the established force, but continue to search for further fundamental forces that may be connected to Dark Matter.
Physicists at Heinrich Heine University Düsseldorf have used ultra-high-precision laser spectroscopy to measure the wave-like vibration of atomic nuclei with unprecedented precision. By studying the molecular hydrogen ion (MHI), they confirmed the wave-like movement of nuclear material and found no evidence of any deviation from the established force between atomic nuclei. The researchers improved experimental precision to a level better than theory, establishing the most precise test of the quantum motion of charged baryons. Their findings provide valuable insights into the behavior of atomic nuclei and could potentially contribute to the search for new physical effects related to Dark Matter.
