This Week in Physics — Realizing the Einstein-Podolsky-Rosen Paradox for Atomic Clouds

This Week in Physics Magazine — May 30, 2023 Viewpoint Realizing the Einstein-Podolsky-Rosen Paradox for Atomic Clouds Margaret D. Reid – May 30, 2023 A new demonstration involving hundreds of entangled atoms tests Schrödinger's interpretation of Einstein, Rosen, and Podolsky's classic thought experiment. Focus Predicting When a Material Will Crack May 26, 2023 A combination of two techniques provides warning signs that the stress on a material will lead to failure. Video Drops Wear Different "Crowns" May 23, 2023 A study of drops falling on a thin liquid film finds that splash behavior depends on film thickness—a result that could impact our understanding of stalagmite formation. synopsis Superconductor Vortices Visible as Stripes May 30, 2023 An unusual kind of superconductor harbors magnetic vortices that researchers predict should be readily observable thanks to the striped configurations they adopt. synopsis Angle and Friction Matter for Table Tennis Spin May 26, 2023 The angle of incidence and the friction of the surface are the only factors that impact the spin of a table tennis ball after it collides with a rigid surface. synopsis "Shuttled" Ions Stay Quantum May 26, 2023 Researchers move an individual Mg+ ion more than 100,000 times between different sites in a trapping array without dropping it or ruining its quantum coherence. synopsis Static Electrons in Flat-Band Nonequilibrium Superconductors May 25, 2023 Single electrons stay stationary in superconductors with "flat-band" electronic structures, which could lead to low-energy-consumption devices made from such materials. synopsis Gravity Alters the Shape of an Evaporating Droplet May 24, 2023 Whether sitting or hanging, the surface of a protein-containing droplet changes as the water escapes, an effect researchers link to the pull of gravity. synopsis Curved-Laser Demonstration for a Higher-Energy Laser Accelerator May 23, 2023 A curved "laser wakefield accelerator" could boost the acceleration potential of a multistage version of this device. Research News Squeezable Metal Offers a Greener Approach to Refrigeration May 30, 2023 A system built around a metal that gains and loses heat when compressed could lead the way to the commercialization of chemical-free refrigeration technology. Research News Survey Finds Cheating Is Common in Graduate School May 25, 2023 In a survey of 244 engineering graduate students, one fifth admit to cheating or committing some form of research malpractice during their studies. Research News Researchers Recreate a Nearsighted Eye May 23, 2023 A new device can recreate the refractive errors of a myopic eye—one that displays nearsightedness—allowing scientists to test lenses designed to slow down the progression of the condition. 1 Physics Ellipse, College Park, MD 20740 © 2023 American Physical Society | All rights reserved View Email Online You are receiving this message because you signed up to receive Physics Magazine email alerts or are a member of APS.
