    First Clues to ‘Impossible’ Magnetic Monopoles Exposed by Diamonds And Rust : ScienceAlert

    The search for the magnetic monopole – a particle with one magnetic pole, not two – is one of the most exciting and potentially transformational quests in physics, and scientists just made a major new discovery in their monopole hunt. An international team of researchers, led by academics from the University of Cambridge in the…

  • Electrical tuning of branched flow of light

    Theory of branched flow of light in liquid crystal film According to the Ericksen-Leslie theory, the optical properties of liquid crystals can be characterized by the spatial distribution of molecules’ orientation vector (or the “director”) \(\hat{{{{{{{{\bf{n}}}}}}}}}({{{{{{{\bf{r}}}}}}}})\)31,32. This unit vector determines the local average molecular orientation. Due to the optical birefringence, a uniform NLC system supports…

    Experimental results Figure 1a shows a schematic of the experimental setup at Vulcan, the details of which can be found in the Methods section. Figure 1e, f, g shows the Au ion spectra obtained using Thomson parabola spectrometers (TPS) directed along three observation lines, from the interaction with a 15 nm (black) and a 30 nm (red)…

  • The Cutting-Edge of Quantum Entanglement

    The Cutting-Edge of Quantum Entanglement

    Two groundbreaking studies have developed a method for controlling quantum entanglement in molecules, specifically calcium fluoride (CaF), using an optical tweezer array to create highly entangled Bell states. This advancement opens new avenues in quantum computing and sensing technologies. Advancements in quantum entanglement with calcium fluoride molecules pave the way for new developments in quantum…

  • Turbulence Modeling No Longer a Drag

    January 2, 2024• Physics 17, s2 A new theoretical framework allows scientists to accurately estimate the friction a surface experiences in a turbulent flow, such as an airplane wing flying through the sky. hlxandr/stock.adobe.com hlxandr/stock.adobe.com × When a fluid flows across a solid surface, friction arises between the fluid and the surface. This friction dictates…
