As researchers from the University of Rostock, Germany have shown, this very human insight also applies to the most fundamental building blocks of nature. https://phys.org/news/2026-01-collaboration-elementary-particles-teamwork-photon.html Optics & Photonics Mon, 26 Jan 2026 15:40:01 EST news688663613 A new international study led by Helmholtz Munich and the University of Rostock reveals that emissions from modern gasoline cars—despite meeting the currently strictest European emission standards EURO 6d—can become significantly more harmful after being released into the atmosphere. The findings, published in Science Advances, challenge the assumption that filtered exhaust from EURO 6d-compliant vehicles is inherently safe. https://phys.org/news/2025-05-filtered-car-emissions-toxic-sunlight.html Environment Wed, 28 May 2025 17:30:04 EDT news667672202 By breaking a decades-old paradigm and rethinking the role that the dimension of time plays in physics, researchers from the University of Rostock and the University of Birmingham have discovered novel flashes of light that come from and go into nothingness—like magic at first glance but with deep mathematical roots that protect against all kinds of outside perturbations. Their findings have now been published in the journal Nature Photonics. https://phys.org/news/2025-04-space-scientists-explore-dimension.html General Physics Wed, 23 Apr 2025 08:53:03 EDT news664617181 Together with an international team of researchers from the Universities of Southern California, Central Florida, Pennsylvania State and Saint Louis, physicists from the University of Rostock have developed a novel mechanism to safeguard a key resource in quantum photonics: optical entanglement. Their discovery is published in Science. https://phys.org/news/2025-03-newly-waveguide-device-photonic-quantum.html Optics & Photonics Thu, 27 Mar 2025 13:10:02 EDT news662289303 A collaboration of Professor Szameit's research group at the University of Rostock with researchers from the Albert-Ludwigs-Universität Freiburg has succeeded in stabilizing the interference of two photons in optical chips with the concept of topologically protected wave propagation.

Previously, it was assumed that such open systems inevitably would exhibit exponential amplification or damping of light and thus lead to the instability of the system. https://phys.org/news/2024-01-team-robust-propagation.html Condensed Matter Wed, 31 Jan 2024 09:33:25 EST news625916002 By using ultrafast laser flashes, scientists at the University of Rostock in collaboration with researchers of the Max Planck Institute for Solid State Research in Stuttgart have generated and measured the shortest electron pulse to date. The electron pulse was created by using lasers to remove electrons from a tiny metal tip and lasted only 53 attoseconds, that is, 53 billionths of a billionth of a second. The event has set a new speed record in man-made control of electric currents in solid materials. https://phys.org/news/2023-01-ultrafast-laser-generate-shortest-electron.html Optics & Photonics Thu, 26 Jan 2023 09:00:03 EST news593946001 Scientists from the University of Rostock, Germany were able to recreate fundamental physical properties from the realm of elementary particle physics in a photonic system. The results are published in Nature Physics. https://phys.org/news/2022-12-particle-physics-humble-glass-chip.html Optics & Photonics Thu, 01 Dec 2022 12:50:03 EST news589121401 Crystals have enthralled humans for thousands of years with their visual beauty and elegant symmetrical shapes, and, more recently, with their numerous technological applications. Fundamentally, these materials are based on a highly regular arrangement of their smallest constituent elements, and the physical properties of crystalline materials depend strongly on the purity of their underlying lattice. https://phys.org/news/2022-09-spiral-dislocation-3d-topological-photonics.html Optics & Photonics Wed, 28 Sep 2022 12:08:03 EDT news583585682 In collaboration with the group of Professor Mordechai Segev (Technion, Israel Institute of Technology), physicists from the group of Professor Alexander Szameit (University of Rostock) have demonstrated a novel type of mechanism that can prevent light waves from spreading freely. So far, the underlying physical effect had been considered far too weak to fully arrest wave expansion. In their recent experiments, the physicists observed that such light localization is nevertheless possible, demonstrating the uncanny sensitivity of wave propagation across a wide range of spatial length scales. Their discovery was recently published in the journal Science Advances. https://phys.org/news/2022-06-physicists-mechanism-freely.html Optics & Photonics Wed, 01 Jun 2022 15:46:40 EDT news573317198 Space, the final frontier. The starship Enterprise pursues its mission to explore the galaxy, when all communication channels are suddenly cut off by an impenetrable nebula. In many episodes of the iconic TV series, the valiant crew must "tech the tech" and "science the science" within just 45 minutes of airtime in order to facilitate their escape from this or a similar predicament before the end credits roll. Despite spending a significantly longer time in their laboratories, a team of scientists from the University of Rostock has succeeded in developing an entirely new approach for the design of artificial materials that can transmit light signals without any distortions by means of precisely tuned flows of energy. They have published their results in Science Advances. https://phys.org/news/2022-05-transparency-demand-artificial-materials-transparent.html Optics & Photonics Tue, 31 May 2022 16:46:20 EDT news573234378 Together with their colleague Professor Stefano Longhi (Polytechnic Institute of Milan), physicists from the group of Professor Alexander Szameit (University of Rostock) have discovered a triple phase transition. At the critical moment, three fundamental properties of an intricate artificial material change abruptly: Topology, conductivity, and energy exchange with the environment. These results challenge the established view that these three major material properties would be largely independent from one another. The discovery was recently published in the journal Nature and could pave the way toward a holistic understanding of the inner workings of complex materials. https://phys.org/news/2022-01-triple-phase-transition-photonic-quasicrystal.html Optics & Photonics Thu, 20 Jan 2022 09:42:03 EST news561894120 Professor Alexander Szameit and his group of physicists from the University of Rostock, in collaboration with Professor Stefano Longhi from the Polytechnic University of Milan, discovered a novel and paradoxical behavior of light waves: Despite being tightly confined in a microscopic volume, a new kind of disorder allows optical signals to suddenly show up at far away regions. Such abrupt transport had previously been considered impossible, and challenges the current understanding of light waves. Their discovery was recently published in the prestigious journal Nature Photonics. https://phys.org/news/2021-06-stop-motion-photons-localized-particles-road.html Optics & Photonics Fri, 18 Jun 2021 10:50:02 EDT news543230178 Microscopes of visible light allow scientists to see tiny objects such living cells. Yet, they cannot discern how electrons are distributed among atoms in solids. Now, researchers with Prof. Eleftherios Goulielmakis of the Extreme Photonics Labs at the University of Rostock and the Max Planck Institute of Quantum Optics in Garching, Germany, along with coworkers of the Institute of Physics of the Chinese Academy of Sciences in Beijing, have developed a new type of a light microscope, called the Picoscope, that overcomes this limitation. https://phys.org/news/2020-07-laser-pictures-electrons-crystals.html Optics & Photonics Wed, 01 Jul 2020 11:00:02 EDT news512818195
