Ett internationellt forskarteam har för första gången direkt observerat överföring av rörelsemängdsmoment i en kristall, vilket avslöjade en oväntad vändning i atomernas rotationsriktning. Upptäckten, som gjordes med kraftfulla terahertz-laserpulser på vismutselenid, belyser en kvanteffekt kopplad till kristallsymmetri. Resultaten publicerades i Nature Physics.

Studien leddes av forskare från Helmholtz-Zentrum Dresden-Rossendorf, Fritz Haber-institutet vid Max Planck-sällskapet samt samarbetspartners i Berlin, Dresden, Jülich och Eindhoven. Forskarna använde extremt starka laserpulser för att driva gittervibrationer i cirkulär rörelse och spårade interaktioner mellan kopplade vibrationer i materialet.

8 april 2026 Rapporterad av AI

Physicists with the STAR collaboration have observed particles emerging directly from empty space during high-energy proton collisions at Brookhaven National Laboratory. The experiment provides strong evidence that mass can arise from vacuum fluctuations, as predicted by quantum chromodynamics. Quark-antiquark pairs promoted to real particles retained spin correlations tracing back to the vacuum.

Scientists uncover 48-dimensional topologies in quantum light

Researchers from the University of the Witwatersrand in South Africa and Huzhou University have discovered hidden topological structures in entangled photons, reaching up to 48 dimensions. These patterns emerge from the orbital angular momentum of light produced via spontaneous parametric downconversion. The findings, published in Nature Communications, suggest new ways to encode quantum information.

Chemists discover bizarre half-Möbius molecular shape

5 mars 2026 Rapporterad av AI

Researchers have created a molecule with a novel topology resembling a half-Möbius strip, requiring four loops to return to the starting point. The structure, made from 13 carbon atoms and two chlorine atoms, was assembled on a gold surface at low temperatures. This discovery highlights potential advances in molecular engineering and quantum simulations.
