Relativistic transport near moving interfaces
Lorenzo Gavassino
The paper studies linear disturbances near planar surfaces moving at constant speed in relativistic media, presenting a propagator-based geometric framework that unifies the descri…
Convergence to the exact kinetics of the one-dimensional Riviera model
Pascal Viot
The paper develops a systematic hierarchy of kinetic equations for the one‑dimensional Riviera random sequential deposition model and shows that finite‑order closures quickly conve…
Variational Formulation of a Hybrid Kinetic and Gyrokinetic Model for Astrophysical and Laboratory Plasmas
F. N. deOliveira-Lopes, S. C. Thatikonda, D. Told +5
The paper introduces a Lagrangian model that couples fully kinetic ions with gyrokinetic electrons to efficiently simulate solar‑wind electromagnetic turbulence, using variational…
Kinetic Linear Stability Theory for High-Speed Compressible Flows: A High Performance Computing Framework
Irmak Taylan Karpuzcu, Deborah Levin, Vassilis Theofilis
The paper develops a kinetic linear stability theory for one‑dimensional normal shocks by linearizing the Boltzmann‑BGK equation and implements a high‑performance parallel solver t…
Imaging non-hydrodynamic modes with jet wakes
Aleksi Kurkela, Ian Moult, Alexander Soloviev +1
The authors propose that the angular pattern of the energy deposited by a jet (the jet wake) in heavy‑ion collisions can be used to detect non‑hydrodynamic excitations of the quark…
A Critical Density Estimate for the Vlasov--Poisson System: Energy Conservation and Moment Propagation
Zhaopeng Wang
The paper proves a critical space‑time density bound for the three‑dimensional Vlasov–Poisson system, showing that weak solutions with finite kinetic energy conserve total energy a…
