The physical mechanisms responsible for the onset of magnetic reconnection during substorms are not well understood. Fully kinetic simulations can resolve the electron-scale physics essential to reconnection, but extending such models to the entire magnetosphere is computationally infeasible. As a result, the location and triggering mechanisms of reconnection must be studied using approaches...

Magnetic reconnection enables rapid energy conversion and particle acceleration in space and astrophysical plasmas. Direct measurements of plasma parameters and particle distributions during reconnection are rare but possible within Earth’s magnetosphere. Satellite observations, however, are limited in both temporal and spatial coverage, while numerical simulations can provide a more complete...

The pressure tensor in a collisionless, magnetised plasma is anisotropic with respect to the guide magnetic field. We derive evolution equations of the perpendicular and parallel pressure components for the case of a relativistically hot plasma. When a plasma is subject to a mean perpendicular flow, these reduce to double-adiabatic laws, with adiabatic indices dependent on the temperature and...

One of the great challenges of plasma astrophysics is understanding the interplay between large- and small-scale dynamics in inherently multiscale phenomena such as turbulence, magnetic reconnection, shocks, and particle acceleration. The vast separation of scales between the fluid-like, macroscopic dynamics and microscopic electron kinetics involved in those processes poses major theoretical...

Plasmas inherently exhibit multiscale dynamics, and full kinetic models are crucial for understanding these complex processes. Explicit kinetic schemes are easy to implement but demand time steps finely resolved to the plasma period and may suffer from numerical heating, while implicit schemes ensure stability but involve costly nonlinear solvers. Semi-implicit methods provide a practical...

Magnetic reconnection in the magnetotail efficiently converts stored magnetic energy into particle energy, yet how this energization spans from kinetic scales to global transport remains an open question. We investigate plasma transport and acceleration from magnetotail reconnection to the inner magnetosphere using a multiscale modeling approach. We employ the energy-conserving ECSIM...

In this talk, I will explore the needs and rationale for using implicit PIC simulations in fusion research. With the resurgence of fusion R&D funding in recent years, there is a need to interpret and understand experimental data from various fusion devices, such as tokamaks, stellarators, pinches, magnetic mirrors, and cusps. Of particular interest, the plasma confinement efficiency of these...

Planets and comets offer unique laboratories for studying the complex interactions between space plasmas and the solar wind. Mercury, the only telluric planet besides Earth with an intrinsic magnetic field, provides a critical case study for examining a dynamic and compact airless magnetosphere. Comets provide invaluable insights into the interactions between the solar wind and outgassing...

Enabling multiscale modelling is a pivotal problem in plasma physics, which entails the need to couple global reduced-order (fluid) models with local, fully kinetic descriptions that capture microscopic particle dynamics. In this presentation, we address this challenge by studying decaying turbulence in the near-Earth magnetosheath using fully kinetic particle-in-cell (PIC) simulations. We...

In this talk, I will introduce Entity, a community-developed, open-source, GPU-accelerated particle-in-cell framework for large-scale simulations of collisionless plasmas. Entity’s grid-agnostic architecture and use of the Kokkos performance portability library enable efficient execution across CPU and GPU platforms, making it a versatile tool for studying plasma environments from laboratory...

Understanding the kinetic properties of strongly nonlinear electromagnetic waves in highly magnetized pair plasmas is essential for establishing the connection between radiation produced near neutron stars and the radiation that ultimately escapes and is observed. In this work, we identify and analyse a previously unaccounted for, to the best of our knowledge, nonlinear process affecting...

Recent studies of weak heliospheric shocks and shocks propagating in relativistic pair plasma have shown that pre-existing turbulence does indeed play a significant role in the shock dynamics and particle acceleration. We present the first 2D3V particle-in-cell (PIC) simulations of electron-ion non-relativistic oblique shocks that explore the interaction of the foreshock with pre-existing...

Plasma mixing across velocity shear layers is a key process controlling mass and momentum transport at planetary magnetospheric boundaries. At the Earth’s magnetopause, the Kelvin–Helmholtz instability (KHI) is expected to facilitate such transport by generating large-scale vortices and turbulence. However, in collisionless, magnetized plasmas, the efficiency of KHI-driven mixing remains an...

Collisionless relativistic shocks are widely invoked as the engines that generate high-energy particles and radiation in some of the most extreme astrophysical environments—most notably, in the late stages of gamma-ray bursts and in pulsar wind nebulae. I will present recent advances in our theoretical and computational understanding of these shocks, with an emphasis on the mechanisms by which...

Solar wind is highly turbulent with energy spreading and cascading over a wide range of scales from the size of the solar system down to electron scales. Recent observations have shown a cascade of energy below the ion-scales extending to the electron scales. We perform iPIC3D simulations of decaying turbulence which show relative abundance of kinetic Alfvén waves (KAWs) at sub-ion scales over...

We model plasma turbulence in the near-Sun solar wind by means of a high-resolution fully kinetic simulation initialised with average plasma conditions measured by Parker Solar Probe during its first solar encounter. Once turbulence is fully developed, the power spectra of the plasma and electromagnetic fluctuations exhibit clear power-law intervals down to sub-electron scales. Our simulation...

Mercury’s magnetosphere is small, highly dynamic, and strongly driven by magnetic reconnection. During the third BepiColombo flyby, the spacecraft observed intense wave activity that appears closely linked to these reconnection processes.
In this work, we investigate the global characteristics of magnetic reconnection at Mercury using two fully kinetic 3D simulations performed with iPIC3D....
