[PUBLICATION #ITFIP] The EARLI collaboration, bringing together IRFU, LPGP, THALES, and CERN, has recently published the design of a high-quality electron injector based on laser wakefield acceleration. The article details the project of this source, including the transport of the electron beams to a second plasma stage for further acceleration, adopting an approach specific to particle accelerator physics. The realization of such a source is a crucial step towards developing a compact electron accelerator capable of accelerating electron beams to very high energies, paving the way for ambitious applications in particle physics.

Read the new paper by Pierre Dalmas de Reotier, Alain Yaouanc, Gerard LAPERTOT, Chennan Wang, Alex Amato, and Daniel Andreica reporting the experimental determination of the spin Hamiltonian of the cubic chiral magnet MnSi. 👉 https://lnkd.in/ephC2beR Helices appear in different systems of condensed matter and biology, like the skyrmion textures observed in chiral magnets with B20 crystal structure, as first discovered in MnSi. A thorough description of the physics of this magnetic compound requires the validation of its microscopic spin Hamiltonian. This study describes the determination of the minimal Hamiltonian for the chiral binary intermetallic magnet MnSi. Our analysis suggests the compound to be still cubic in its magnetically ordered state. Our microscopic magnetic picture could be of interest, for example, for an insight into the partial magnetic order observed above Tc under pressure, or the mechanisms at play for the stabilization of the skyrmion crystal and related topological Hall and Nernst effects.

Unlocking the Fourth Dimension: How Synthetic Dimensions Are Redefining Physics Researchers developed adjustable arrays of waveguides that introduce synthetic modal dimensions, enhancing the management of light within photonic systems. This innovation has potential applications ranging from mode lasing to quantum optics and data transmission. In the realm of physics, synthetic dimensions (SDs) have emerged as a cutting-edge research frontier, providing a means to investigate phenomena in higher-dimensional spaces beyond our conventional 3D geometry. This concept has gained substantial attention, particularly in topological photonics, due to its potential to reveal complex physics that cannot be accessed within traditional dimensions.

🚀 Excited to have completed an insightful summer school course on Quantum Mechanics for Photonics! 🌟 A huge thanks to Dr. Maksim Shundalau from the University of Salerno, Italy, for leading this course. Hosted by the University of Eastern Finland, the course provided an in-depth exploration of the quantum mechanics underlying molecular systems and low-dimensional materials. The course also included hands-on modeling of the structure and different properties of diatomic and polyatomic molecules, using Quantum ESPRESSO and GAMESS software. #QuantumMechanics #Photonics #MolecularSystems #LowDimensionalMaterials #QuantumESPRESSO #GAMESS #DFT #MolecularModeling #UniversityOfEasternFinland #LifelongLearning

Our new work, published yesterday in Communication Physics (NPG), reports the solution to a persistent problem: How to attain maximum transmission of light through a deep-subdiffractional single hole. In the reported full-3D topological / nonreciprocal structures we find, quite remarkably, almost 100% transmission through a hole smaller than one 1000th of the incident wavelength! (even smaller compared with the free-space wavelength) – Fig. 4(c), upper panel. Moreover, the effect is completely immune to surface roughness, defects, dispersion, and even nonlocal effects – which we study in some detail in the article. It is the first time that such a 3D topological ‘extraordinary optical transmission’ (EOT) is reported, with conceivable applications for nanoscale optical microscopy and heat-assisted magnetic recording (HAMR).

🧲 Physicists and engineers are working to improve positron sources to advance the development of future lepton colliders, such as the proposed Future Circular Collider (FCC) at CERN. Among these efforts is the PSI Positron Production (P-cubed) experiment. Paolo Craievich and his team at the Paul Scherrer Institut PSI have developed a novel positron source to be implemented at PSI's X-ray free-electron laser, SwissFEL, that could increase the current positron yield by an order of magnitude. The P-cubed team expects the source to be fully operational by 2026. The P-cubed experiment has garnered attention and was recently featured in an article on physicsworld titled “New positron source could give lepton colliders a boost.” To learn more about the P-cubed project and its impact on future colliders, read the full article 👇 The experiment has also recently been published in a paper in Physical Review Accelerators and Beams: https://lnkd.in/daUBwTGK CC: Mariia Zykova, Nick Strohmaier, Nicolas Vallis, Riccardo Zennaro, Mattia Schaer and Paolo Craievich. #ResearchAtPSI #SwissFEL #FELs #freeelectronlasers
