Plasma Physics

Zack Gelles examines how black-hole rotation twists magnetic fields near light cylinders, where plasma accelerates into inflows and outflows. Semi-analytic models and simulations connect this structure to polarization changes detectable with radio interferometry, offering constraints on black-hole spin and relativistic jets. Kritti Sharma presents fast radio bursts as probes of cosmic baryons. Dispersion measures and secure host redshifts constrain gas in galaxy groups and clusters, while correlations with large-scale structure and other tracers map matter along burst sight-lines. The talk considers how future burst surveys can measure baryonic feedback and its evolution alongside other cosmological observations. Online via Stanford KIPAC Zoom. Friday 25 September 2026, 10:40–11:30 PDT (America/Los_Angeles; UTC−7). Follow Join the zoom meeting on the event page. The organizer lists faculty, staff, members and students as the audience. This is one session with two speakers; individual talk start times are not supplied.

The APS plasma-physics meeting is held jointly with the Gaseous Electronics Conference. Its programme combines invited research reviews, contributed presentations, posters and mini-conferences across magnetic fusion, high-energy-density and laser-plasma physics, astrophysical plasmas and low-temperature plasma science. Experimental measurements, theory and computation address plasma stability, transport, material response and confinement. The opening review by Riccardo Betti (University of Rochester, Laboratory for Laser Energetics) examines a decade of OMEGA direct-drive implosions: pressure and fusion-yield improvements, hydrodynamic extrapolation to ignition, and the limits of that scaling. It connects improved microphysics, diagnostics, targets and statistical design with the balance between compression and three-dimensional stability, then considers broadband lasers and hybrid targets as routes toward higher gain. Troy Carter (Oak Ridge National Laboratory) chairs this session. The DPP scientific programme runs November 2–6, 2026 at Hilton Chicago, 720 South Michigan Avenue, Chicago. The opening review is November 2, 08:00–09:00 America/Chicago (CST, UTC−06:00). Registration offers in-person and virtual attendance. Invited sessions are livestreamed with Q&A; virtual-only sessions and ePosters are included, with invited/virtual session recordings available for 60 days. Contributed oral sessions and mini-conferences are neither streamed nor recorded. Registration requires an APS account and is open to members and nonmembers. Listed adult full-plan member fees range from USD 890 to 1,040 in person and USD 630 to 780 virtually; nonmember/basic-plan adult fees range from USD 1,080 to 1,230 and USD 760 to 910 respectively. Student and retired rates differ; undergraduate full-plan members register free. Check the registration portal for the applicable current rate. Optional special events cost extra. Cancellations are due October 19 with a USD 50 deduction; banquet tickets are nonrefundable.
