In a collisionless shock\, collective fields provide complex nonlinear and kinetic interactions that can suppor t collisionless/anomalous heating mechanisms in the plasma. Consequently\, there is no generally accepted theory of particle energy partitioning and heating in collisionless shocks. Electron and ion temperatures are obtain ed by spacecraft measurement of planetary bow-shocks and analysis supernov a remnant spectra exhibit large statistical variance of the inferred energ y partition\, and particle-in-cell simulations often cannot reproduce elec tron-ion temperature ratios measured in nature. Laboratory experiments off er a complementary approach to satellite measurements and astronomical obs ervations.\nIn this talk\, I will present results from magnetized collisio nless shock laboratory experiments at conditions relevant to planetary bow -shocks (MA~ 8\,  ~ 3). We report the first laboratory observation of f ully developed shocks (×3.6 compression ratio and a downstream region dec oupled from the piston). The data indicate the presence of a foot ahead of the density discontinuity\, where both electrons and ions exhibit signifi cant super-adiabatic heating. Surprisingly\, the downstream exhibits signi ficant super-adiabatic heating of both species with electrons and ions in thermal equipartition\, with an order-unity electron-ion downstream temper ature ratio Te/Ti ~ 0.8. This temperature ratio is inconsistent with a com bination of adiabatic compression and electron-ion collisional equilibrati on\; thus\, it provides the first laboratory evidence of collisionless ano malous heating in a fully developed perpendicular magnetized collisionless shock [1].\n\nReferences\n[1] Valenzuela-Villaseca\, et al.\, “Laborato ry measurements of energy partitioning and anomalous electron heating in m agnetized\, perpendicular collisionless shocks”\, in review at The Astro physical Journal.

Satellite products representin g phytoplankton chlorophyll\, derived from ocean colour observations\, are widely used in operational marine ecosystem prediction as a proxy for phy toplankton biomass. However\, phytoplankton carbon products\, although lon g available\, are not yet widely assimilated. A new phytoplankton carbon p roduct from the ESA-funded BICEP project has recently been derived through an alternative processing of ocean colour\, providing complementary infor mation on phytoplankton biomass to chlorophyll alone. We therefore expect that assimilating phytoplankton carbon\, especially together with chloroph yll\, can provide a more balanced update to the marine ecosystem state.\nI n this talk\, I will present the development of a global ensemble DA syste m based on the coupled ocean–biogeochemistry model NEMO-MEDUSA and the P arallel Data Assimilation Framework (PDAF). PDAF provides a flexible and e fficient infrastructure for implementing ensemble-based DA\, allowing us t o assimilate new biogeochemical variables and evaluate time-dependent fore cast uncertainty in a global marine ecosystem model. In addition\, we will introduce a newly developed diagnostic tool that is used to quantify the uncertainties in observation and forecast errors. We will demonstrate its application to the errors of the new carbon product and their correlations with errors in the chlorophyll products. The results highlight both the p otential value of phytoplankton carbon assimilation and the importance of flexible ensemble DA frameworks for developing future marine ecosystem pre diction systems.

We push on the world\, and the world pushes back. More than a century ago\, scientists discovered that some experiments pro duced a startling result: the world is quantum.\nQuantum theory is famousl y strange\, yet we now understand it well enough to put it to work. Quantu m technologies aim to harness and control the quantum world in ways that c an make us wealthier\, healthier and safer. In this talk\, Professor Milbu rn will describe the quantum technologies that are already beginning to ch ange our lives\, including quantum computing. Looking ahead\, he will expl ore how the combination of quantum computing and embedded artificial intel ligence could create “self-driving laboratories” that accelerate scien tific discovery and open the door to technologies beyond our current imagi nation.\nPlease note – online attendance is now also available\, and reg istration for this is essential through the following link:  https://www. eventbrite.co.uk/e/online-public-talk-quantum-learning-quantum-quantum-com puters-and-ai-tickets-1993782281475\nThe speaker\nProfessor Gerard Milburn FRS is one of the world’s leading quantum physicists and a pioneer of quantum computing research. Over a career spanning more than four decades\ , he has helped shape the development of technologies that harness the unu sual properties of the quantum world to process information in entirely ne w ways. His work has contributed to many of the foundational ideas behind modern quantum computing and quantum technologies.\n\n\nA Fellow of the Ro yal Society\, Professor Milburn has held senior leadership roles at major international research centres and is currently Quantum Fellow at the UK ’s National Quantum Computing Centre\, where he helps guide the UK’s q uantum computing programme and its future applications in science and soci ety.\n \n\n\n\nThe Main talk starts at 7pm. Refreshments will be served b efore the talk from 6:00pm. The audience is invited to participate and ask questions following the talk.\n\nThis event has been organised by the Hub bard Theory Consortium.\n\n URL:/events/211377/quantum-learning-quantum-quant um-computers-and-ai/ DTSTART;TZID=Europe/London:20260722T180000 DTEND;TZID=Europe/London:20260722T200000 LOCATION:Lecture Theatre 1\, Blackett Building\, South Kensington Campus\, 91ɫ\, London\, SW7 2AZ\, United Kingdom END:VEVENT BEGIN:VEVENT UID:a242098d0c27161f1c8fcde91446a18b DTSTAMP:20260718T051514Z SUMMARY:Attosecond ionization dynamics: from perturbative to strong field. DESCRIPTION:Speaker\nProfessor Alexandra Landsman\nThe Ohio State Universit y\nAbstract:\nRecent advances in X‑ray free‑electron laser (XFEL) tech nology have opened new opportunities to probe photoionization dynamics on attosecond timescales and to access strong‑field regimes at X‑ray wave lengths that were previously experimentally inaccessible. In this talk\, I will discuss two complementary classes of XFEL experiments that together illuminate the timing and mechanisms of electron emission in atoms and mol ecules.  First\, I will address attosecond photoemission delays measure d using circular streaking techniques\, with a focus on extending ionizati on‑delay chronoscopy from linearly to circularly polarized probes.  I will also address the challenges of interpreting streaking delays at low photoelectron energies.  Second\, I will present recent theoretical work exploring a new non‑perturbative strong‑field X‑ray regime\, where multiphoton above‑threshold ionization (ATI) is driven by attosecond XFE L pulses. In helium\, this regime produces distinct angular and spectral s ignatures that are clearly separated from perturbative harmonic contributi ons.  Together\, these studies demonstrate how XFELs enable both quantit ative attosecond chronoscopy and fundamental tests of strong‑field ion ization physics at short wavelengths\, establishing a foundation for futu re experiments in atoms and molecules.\n Alexandra Landsman\nProfessor of Physics\nThe Ohio State University\nDepartment of Physics\nPhysics Resear ch Building\n191 W Woodruff Ave\, Columbus\, OH 43210\n  URL:/events/211480/attosecond-ionization-dynamics -from-perturbative-to-strong-field/ DTSTART;TZID=Europe/London:20260724T120000 DTEND;TZID=Europe/London:20260724T130000 LOCATION:B630\, Blackett Building\, South Kensington Campus\, 91ɫ Coll ege London\, London\, SW7 2AZ\, United Kingdom END:VEVENT BEGIN:VTIMEZONE TZID:Europe/London BEGIN:DAYLIGHT DTSTART:20260717T090000 TZNAME:BST TZOFFSETTO:+0100 TZOFFSETFROM:+0100 END:DAYLIGHT END:VTIMEZONE BEGIN:VTIMEZONE TZID:Europe/London BEGIN:DAYLIGHT DTSTART:20260721T110000 TZNAME:BST TZOFFSETTO:+0100 TZOFFSETFROM:+0100 END:DAYLIGHT END:VTIMEZONE BEGIN:VTIMEZONE TZID:Europe/London BEGIN:DAYLIGHT DTSTART:20260721T113000 TZNAME:BST TZOFFSETTO:+0100 TZOFFSETFROM:+0100 END:DAYLIGHT END:VTIMEZONE BEGIN:VTIMEZONE TZID:Europe/London BEGIN:DAYLIGHT DTSTART:20260722T180000 TZNAME:BST TZOFFSETTO:+0100 TZOFFSETFROM:+0100 END:DAYLIGHT END:VTIMEZONE BEGIN:VTIMEZONE TZID:Europe/London BEGIN:DAYLIGHT DTSTART:20260724T120000 TZNAME:BST TZOFFSETTO:+0100 TZOFFSETFROM:+0100 END:DAYLIGHT END:VTIMEZONE END:VCALENDAR
