This was the conclusion of a study published in Astronomy and Astrophysics and directed by Riccardo Valdarnini of SISSA’s Astrophysics and Cosmology group. Using numerical simulations, the study analyzed what happens …
Crystal structures and electronic localization function of H4OF2 and H4OF2·HF. Credit: Physical review B (2024). DOI: 10.1103/PhysRevB.109.174102 Skoltech scientists and their Chinese colleagues have determined the conditions that enable the existence of a very special ion. Called aquodiium, it can be thought of as an ordinary neutral water molecule with two extra protons stuck to …
Schematic of the experimental setup. Credit: science (2024). DOI: 10.1126/science.adn7087 Researchers have for the first time observed a timing crystal on a small-scale semiconductor chip oscillating at a rate of several billion times per second, revealing extremely high nonlinear dynamics in the GHz range. The results of the experiment, published in scienceestablish a strong link …
