Dr Adam Kirrander: Theoretical and experimental advances in ultrafast x-ray scattering

9:30am, Virtual (contact the host for a Zoom link)

New x-ray and electron scattering experiments provide a window onto ultrafast photochemical and photophysical dynamics. I will review recent experimental advances, including recent measurements of excited-state molecular structures [1] and observation of the changes in electron density associated with photoexcitation of a molecule [2]. Moving to computations and theory, we will look at how scattering cross-sections can be calculated and the physical insights we can draw from each type of scattering. In particular, we will discuss how experiments that transgress the distinction between structural dynamics and spectroscopy can be achieved. As an example, we will look at simulations of an experiment that tracks electron transfer and transient electronic coherences in a molecule using x-ray scattering.[3]

Hugo Lavenant: Hidden convexity in a problem of nonlinear elasticity

12:00pm, zoom

The talk will be about compressible and incompressible nonlinear elasticity variational problems. Our contribution is to provide a convex relaxation for a class of non convex problem, together with sufficient conditions guaranteeing its tightness. Our relaxation is based on a notion of Dirichlet energy for measure valued mappings which is interesting in itself, and the proof of tightness relies on convex analysis and the study of a dual problem. 

This is joint work with Nassif Ghoussoub, Young-Heon Kim and Aaron Palmer (UBC):

Joel Dahlin: Explosive Energy Release in the Solar Corona


Recent advances in solar instrumentation have revealed a rich variety of eruptive activity in striking detail. The largest such eruptions, coronal mass ejections and associated solar flares, drive the shocks and energetic particles that play a major role in the most hazardous space weather events. To predict the space weather impact of solar eruptions, we must understand three vital questions: How does energy build up in the corona? What triggers its explosive release? How is that energy transferred to nonthermal particles? To accurately model explosive activity, it is important to capture both the large-scale dynamics of the energy buildup and release and the fine-scale structure that plays a critical role in particle energization. I present recent advances in tackling these questions using high-resolution, three-dimensional magnetohydrodynamics simulations of solar eruptions. I also discuss promising avenues for future work and prospects for comparison to ground-based (DKIST, EOVSA) and space-borne (PSP, SolO) observations.
