SAPPHIRE Breakthrough: Scientists Capture Plasma Movies at 100 Billion Frames Plasma, often described as the fourth state of matter , makes up more than 99% of the visible universe. From blazing stars to advanced semiconductor manufacturing, understanding plasma behaviour is crucial. Yet probing this volatile, ionized gas has long been a scientific challenge, as its changes occur in mere trillionths of a second. Now, researchers at Lawrence Livermore National Laboratory (LLNL) has unveiled a revolutionary diagnostic technique called SAPPHIRE (Single-shot Advanced Plasma Probe Holographic Reconstruction) . Published in Optica , this study showcases the ability to record plasma dynamics with a single laser shot - creating "movies" at an astounding 100 billion frames per second . For more on cutting-edge scientific innovations, readers can also explore FSNews365 where groundbreaking discoveries across technology and science are regularly covered.

New Magnetic Discovery: Unraveling the Lyddane-Sachs-Teller Relation's Counterpart Understanding the Lyddane-Sachs-Teller Relation Materials exhibit distinct interactions with electromagnetic fields, revealing their structural and intrinsic properties. The Lyddane-Sachs-Teller relation describes the correlation between a material's static and dynamic dielectric constants — parameters defining its response to external and absent electric fields —and the vibrational modes of its crystal lattice , characterized by resonance frequencies. Origin of the Lyddane-Sachs-Teller Relation Originally formulated by physicists Lyddane, Sachs, and Teller in 1941, this theoretical framework has become a cornerstone of solid-state physics and materials science. It has significantly contributed to understanding material properties, facilitating the development of advanced electronic devices. Expanding the Lyddane-Sachs-Teller Relation into Magnetism A research team at Lund University has expand...
