📝 New platforms for ultraconfined plasmons and optical coupling to external light Researchers at ICFO tackle the problem of light confinement in nanocavities from two different perspectives. First, they successfully realize high-quality ultrathin crystalline metal structures that can support spatially compressed plasmons; and second, they demonstrate an efficient technique to couple light to confined surface plasmons. The initial idea of ICREA Prof. at ICFO Javier García de Abajo and his group members Saad Abdullah, Eduardo J. C. Dias, Jan Krpenský and Vahagn Mkhitaryan materialized in a successful experiment, now published in ACS Photonics. In this study, they demonstrate a new method that couples light to flat surface plasmons more effectively than previous strategies. ICFO News 👉 https://bit.ly/3zlWiv1

Remote sensing incorporates a spectrum of photonics technologies that is as diverse as it is effective. Focusing on core and novel applications, as well as core methods. #AllThingsPhotonics S8E7: Though practitioners of precise measurement deploy numerous modalities to obtain this essential information, remote sensing incorporates a spectrum of photonics technologies that is as broad and diverse as it is ubiquitous and effective. Joseph Shaw, director of the Optical Technology Center at Montana State University, overviews remote sensing technology, with a focus on core and novel applications, as well as core methods. In a bonus segment, Sanathana Konugolu Venkata Sekar, cofounder of BioPixS, discusses the company’s biophotonics phantom technology platform.

Dear colleagues, I would like to draw your attention to the release of our comprehensive review on dielectric photonics, in which we tried to include important achievements in this area obtained in recent years. The results under review are based on the so-called Mie resonances, which are a consequence of the resonant interaction of light with nanostructures and allow us to explain and predict optical phenomena on different spatial scales. https://lnkd.in/eZ8zkA2y

I'm very happy to have contributed to this experimental effort to push the limits of resolution of X-ray Thomson scattering measurements at the European XFEL to study plasmon excitations in aluminum. #Materials #XRTS #XFEL Read more about this in the paper:  https://lnkd.in/esB-ZnWE

Warm dense matter (#WDM) can be found in astrophysical objects and is created during inertial confinement fusion. An important method to investigate WDM is X-ray Thomson scattering. Researchers from European XFEL, the Center for Advanced Systems Understanding (CASUS) at HZDR and Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have now recorded ultra-high-resolution X-ray Thomson scattering spectra with an energy resolution improved more than tenfold compared to previous approaches. The team have published their findings in the journal Physical Review B, which honored the work with an “Editor’s Suggestion”. As the researchers report, the innovative method will enable WDM diagnostics with unprecedented accuracy. “These exciting new capabilities at the European XFEL allow for unprecedented insights into the behavior of matter at extreme conditions,” explains lead author Thomas Gawne from CASUS' Young Investigator Group “Frontiers of Computational Quantum Many-Body Theory” led by Tobias Dornheim. Dornheim recently received funding for a laser fusion project from the #EuropeanUnion via its #JustTransitionFund. Specifically, he plans to make X-ray Thomson scattering evaluation accessible beyond the small group many-body system simulation experts. If he succeeds, laser physicists at European XFEL and elsewhere could design their experiments in a more targeted manner than it is possible today.

It was an absolute highlight to provide the theory for this impressive experiment. We used a multi-physics approach to model each step of the experiment from real-time TDDFT to surface hopping and coupled-cluster theory. We extract not just spectral data about geometry changes and electronic character, but also resolve the creation and dephasing of electronic and nuclear quantum beats – the inherent characteristics of coherent superpositions of molecular eigenstates. Work done during my time at Max Planck School of Photonics, Friedrich Schiller University Jena. #chemistry #attosecondscience #physics

Check out our recent paper on ACS Photonics, where we present an experimental method to explore the rotational diffusion of small gold nanorods (5 nm x 15 nm). In this paper, we have shown that the plasmonic coupling of two gold nanorods not only increases the signal-to-noise ratio of the scattered signal but also increases the sensitivity of orientation changes of the gold nanorods in comparison to the confocal measurement of single gold nanorods! https://lnkd.in/dAxk82nC

Quantum Photonics Leap: Revolutionary Nanocavities Redefine Light Confinement Dr. Hanan Herzig Sheinfux, from Bar-Ilan University: “What started as a chance discovery, may well open the way to new quantum applications, pushing the boundaries of what we thought was possible.” In a significant leap forward for quantum nanophotonics, a team of European and Israeli physicists, introduces a new type of polaritonic cavities and redefines the limits of light confinement. This pioneering work, detailed in a study published today (February 6) in Nature Materials, demonstrates an unconventional method to confine photons, overcoming the traditional limitations in nanophotonics, continue reading https://lnkd.in/dz5GGZfv
