Meeting of the Laserlab-Europe expert group on laser-generated EMP
2025-11-27 - 2025-11-28
The Laserlab-Europe Expert Group on laser-generated electromagnetic pulses (EMPs) will be holding their regular workshop at the Rutherford Appleton Laboratory this year. It will be a two day event, featuring oral and poster presentations and ending with a round table discussion.
In experiments involving high power lasers, a significant portion of the incoming laser energy is converted into transient electromagnetic pulses (EMPs), composed of radiation at radio, microwave and THz frequencies. These EMP fields scale with laser energy and intensity and can easily exceed the MV/m magnitude – strong enough to disrupt or imperil electronic devices placed near the experimental vacuum chamber.
The physics of EMP production is closely related to many topics of active research within the laser-plasma community. At previous meetings of the Laserlab expert group we have had talks on a range of fascinating subjects, including: the physics of target charging and fast currents, generating strong magnetic fields with lasers, ion acceleration and beam transport, radiobiological studies, terahertz radiation from solid targets, electromagnetic compatibility (EMC) and techniques for reducing EMP emission.
The workshop will take place on 27 and 28 November 2025 in the Visitor Centre of the Rutherford Appleton laboratory.
The link to register for the conference is here: https://forms.office.com/e/BPpJ6Xs7Pr
Registration deadline: Friday, 26 September 2025
If you would prefer to submit your abstract after you have registered, then send the abstract to philip.bradford@stfc.ac.uk before close of day on Friday 3rd October. Please indicate in your email whether you would like to be considered for an oral or poster presentation.

X-lites Incubator Workshop: Structured Light at High Intensity
2026-02-06 - 2026-02-07 | Ottawa, Canada
Why this workshop matters
Over the past decade, structured light has rapidly expanded—especially in the high-intensity regime, where it opens new frontiers in physics, technology, and interdisciplinary collaboration. This workshop will convene researchers from universities, national laboratories, and light-source facilities to:

Foster community at the intersection of structured light, ultrafast optics, and high-intensity physics;
Catalyze collaboration and align research goals across small, mid-scale, and large-scale facilities;
Launch joint initiatives and a shared roadmap for advancing structured-light science.

Scope and topics
Structured light refers to optical fields whose amplitude, phase, polarization, or temporal profile are deliberately sculpted, often on the scale of a single optical cycle, to introduce four-dimensional spatiotemporal structure. By coupling light’s spatial and temporal degrees of freedom, structured light offers unprecedented control over light-matter interactions.
While traditional laser science has emphasized smooth, Gaussian beams, structured-light methods intentionally introduce spatial and temporal complexity, encoding angular momentum, spatial chirality, and ultrafast modulation, to uncover new regimes of optical control.
High intensity denotes fields strong enough to ionize matter, generate plasma, and trigger nonlinear or relativistic effects, unlocking new physics and enabling novel applications in ultrafast and strong-field science.

Registration closes Jan 7, 2026

Conference Description
The Structures, Energetics and Reaction Dynamics of Gaseous Ions GRC is a premier, international scientific conference focused on advancing the frontiers of science through the presentation of cutting-edge and unpublished research, prioritizing time for discussion after each talk and fostering informal interactions among scientists of all career stages. The conference program includes an array of speakers and discussion leaders from institutions and organizations worldwide, concentrating on the latest developments in the field. The conference is five days long and held in a remote location to increase the sense of camaraderie and create scientific communities, with lasting collaborations and friendships. In addition to premier talks, the conference has designated time for poster sessions from individuals of all career stages, and afternoon free time and communal meals allow for informal networking opportunities with leaders in the field.
Gaseous ions play a pivotal role in various environments, serving as crucial intermediates in processes ranging from atmospheric chemistry to astrophysical phenomena to industrial processing and forensics. In planetary atmospheres, ions contribute to chemical reactions that influence weather patterns, auroras, and even the formation of atmospheric layers. In the interstellar medium, they are central to the formation of complex molecules and the ionization of interstellar gases, thereby affecting star formation and the evolution of galaxies. In combustion, gaseous ions participate in the complex chemistry of flames, impacting energy release and pollutant formation. Beyond these natural contexts, gaseous ions are vital in mass spectrometry, a key enabling technology that underpins numerous scientific fields. Mass spectrometry allows for the precise analysis of substances by ionizing molecules and measuring their mass-to-charge ratios. This technique is indispensable in proteomics for identifying proteins, in metabolomics for studying biochemical pathways, in environmental science for detecting pollutants, and in the emerging field of personalized medicine. In forensics, mass spectrometry is used for drug detection and crime scene analysis, while in pharmaceuticals, it is employed for drug development and quality control. The ability to generate and analyze gaseous ions has revolutionized these areas, providing insights that are critical for research, industry, and beyond.
This GRC focuses on the fundamentals of gas-phase ion chemistry and applications in which gas-phase ion chemistry and physics play a pivotal role. The meeting emphasizes the development of new and the use of more mature experimental and theoretical approaches for studying the structures, energetics, and reactivity of gaseous ions and their applications to systems ranging from atomic ions to complex macro- and bio-molecular assemblies. The conference highlights experimental techniques, including mass spectrometry, optical spectroscopy, and ion mobility that enable elucidation of the intrinsic properties of both simple and complex systems. The conference includes the development of new theoretical techniques as well as the use of well-developed computational approaches in support of experimental measurements. Topics included are structural characterization of gaseous ions; fundamentals of ionization, activation, and dissociation; ion-molecule, ion-ion, ion-electron, and ion-surface interactions; ion reactivity in various environments; and a multitude of applications involving ions.

Laserlab-Europe Talk: Laser processing of functional micro/nanostructures for photonics, optoelectronics, and smart surfaces
2026-02-25 16:00 - 17:00 (Europe/Berlin) | Online
Speaker: Maria Kandyla (National Hellenic Research Foundation)
The need for advanced materials and systems with new functionalities has motivated the development of micro/nanostructures on solid surfaces, which are necessary for the fabrication of functional devices for novel applications. In this talk, we will discuss the development of functional micro/nanostructures, based on laser-processed surfaces.
Coating micro/nanostructures with thin metallic films results in plasmonic substrates with enhanced electromagnetic response across the entire visible range, which are used for plasmonic optical trapping [1]. Combining silicon micro/nanostructures with thin semiconducting films results in electronic heterojunctions with increased surface area for improved optoelectronic performance [2]. Furthermore, isotype heterojunctions result in wavelength-selective, high-speed photodetectors with self-powered operation, which can be further engineered by careful selection of the electronic properties of the constituting materials [3,4]. “Smart” surfaces of controllable extreme wetting states are obtained by combining photoresponsive metal oxides with laser-processed micro/nanostructured substrates, which can reach complete water repellence without chemical modification [5]. Also, surfaces with controlled topography, either at the micro- or at the nano-scale, for targeted cell cultures for biomedical applications [6]. We will present recent advances in these fields and discuss future applications.

ELIXIR2026
2026-03-09 - 2026-03-11 | Saint-Aubin, Saint-Aubin, France
The ELIXIR2026 workshop will take place at SOLEIL from March 9 to 11, 2026.
The development of vacuum-compatible liquid sampling sources has enabled the use of ionizing radiation sources (XUV and X-rays) to study a variety of phenomena in solution, such as reaction dynamics, solvation, or interfacial chemistry. This development is constantly evolving with improvements in light sources, such as the relative democratization of laser sources based on high-order harmonic generation, and improvements in liquid targets with for instance the recent development of stable flat liquid jets with sub-micrometer thicknesses.
The spectroscopic tools available are now extremely varied and reflect the diversity of the scientific communities interested in the study of liquid-phase phenomena at the molecular scale. They include time-resolved photoemission spectroscopy (femtosecond and even attosecond), highly nonlinear optics via liquid-phase HHG, probes of chirality (circular X-ray dichroism, PECD), RIXS, coincidence measurements (e-,e-), etc.
This workshop will bring together users of these different tools. It will also provide an opportunity to compare and improve theoretical aspects of molecular dynamics in the liquid phase, thanks to the participation, we hope, of European experts in the field.

RIANA webinar "Small-Angle Scattering Applied to Bio and Nanomaterials"
2026-03-12 15:00 - 17:00 | Online
Speaker: Debasish Saha, Juelich centre for Neutron Science (JCNS), Forschungszentrum Juelich GmbH, Germany
Small-Angle Scattering (SAS) is a powerful technique that provides information about the structural organization of matter and intra- and or intermolecular interactions in the system at different external conditions. The length scales obtained from the analysis of SAS data are within the limit of a few nanometers to a few hundred nanometers. Among different SAS techniques, Small-Angle X-ray Scattering (SAXS) provides excellent resolution and shorter measurement time, enable us to study different in situ formation of nanomaterials.
However, such benefits are mostly limited to high atomic number (Z) materials, whereas provides poor contrast for low-Z materials, especially for biological systems. On the other hand, the isotope labelling and solvent-contrast variation in Small-Angle Neutron Scattering (SANS) gives an excellent opportunity to extract unique information of individual components in multi-component heterogenous complexes. In addition, the magnetic moment of neutrons allows to study magnetism and magnetic materials at the nanoscale using the magnetic-SANS technique. In this talk, the basics of small-angle scattering and its applications in bio and nanomaterials will be discussed.

Dear colleagues,
Abstract submission for the Focus Session on Interfacial Charge, Spin, and Chemical Dynamics in Energy and Quantum Materials at the APS March Meeting in Denver, CO, USA (March 15-20, 2026) is now open until October 23. We would like to invite you to submit your abstract to this session (number 16.01.09, in DCOMP) to highlight recent progress in theory and simulation methods and their application to modeling dynamics at solid-solid interfaces, including 2D materials, topological materials, and solid-gas phase interfaces of relevance to energy and quantum materials, as well as experimental studies to be interpreted through or integrated with such computational approaches.
We expect this session to bring together contributions from research on method development and its application to the simulations of charge, spin, and chemical dynamics and energy, charge, and spin transport through materials interfaces, including those of organic and hybrid organic/inorganic structures and devices. This session will include theory and method development for electron-phonon coupling, spin-orbit interactions, and excited state dynamics for solid surfaces and interfaces, and for machine-learning models for accelerated prediction of complex interfacial dynamics including non-adiabatic processes and quantum coherent phenomena. It will also include experimental studies that elucidate the dynamics and transport at these interfaces.
We look forward to seeing you in Denver,
Oliver Monti, Johannes Voss, Aiichiro Nakano and Duy Le
