Statistical study of energy dissipation in magnetic structures during turbulent reconnection in the Earth's magnetotail
Rachel Wang, Hantao Ji, Adam Robbins +7
Magnetic reconnection is a ubiquitous plasma phenomenon that plays a critical role in particle heating and energization. During reconnection, the topology of magnetic field rearran…
Automatic Identification of Magnetospheric Regions using Supervised Machine Learning Models
Narges Ahmadi, Robert Ergun, Xiangning Chu +1
We present an automated approach for identifying magnetospheric regions using supervised machine learning techniques applied to Magnetospheric MultiScale mission data. Our method u…
Multi-scale observation of magnetotail reconnection onset: 2. microscopic dynamics
K. J. Genestreti, C. Farrugia, S. Lu +23
We analyze the local dynamics of magnetotail reconnection onset using Magnetospheric Multiscale (MMS) data. In conjunction with MMS, the macroscopic dynamics of this event were cap…
Multi-scale observation of magnetotail reconnection onset: 1. macroscopic dynamics
K. J. Genestreti, C. Farrugia, S. Lu +22
We analyze a magnetotail reconnection onset event on 3 July 2017 that was observed under otherwise quiescent magnetospheric conditions by a fortuitous conjunction of six space and…
The Dynamics of a High Mach Number Quasi-Perpendicular Shock: MMS Observations
H. Madanian, M. I. Desai, S. J. Schwartz +12
Shock parameters at Earth's bow shock in rare instances can approach the Mach numbers predicted at supernova remnants. We present our analysis of a high Alfvén Mach number ($M_A= 2…
Topological and non-topological features of generalized Su-Schrieffer-Heeger models
N. Ahmadi, J. Abouie, D. Baeriswyl
The (one-dimensional) Su-Schrieffer-Heeger Hamiltonian, augmented by spin-orbit coupling and longer-range hopping, is studied at half filling for an even number of sites. The groun…
Multi-scale coupling during magnetopause reconnection: the interface between the electron and ion diffusion regions
K. J. Genestreti, Y. -H. Liu, T. -D. Phan +15
Magnetospheric Multiscale (MMS) encountered the primary low-latitude magnetopause reconnection site when the inter-spacecraft separation exceeded the upstream ion inertial length.…
Electron Heating by Debye-Scale Turbulence in Guide-Field Reconnection
Yu. V. Khotyaintsev, D. B. Graham, K. Steinvall +14
We report electrostatic Debye-scale turbulence developing within the diffusion region of asymmetric magnetopause reconnection with moderate guide field using observations by the Ma…
In situ spacecraft observations of a structured electron diffusion region during magnetopause reconnection
Giulia Cozzani, Alessandro Retinò, Francesco Califano +18
The Electron Diffusion Region (EDR) is the region where magnetic reconnection is initiated and electrons are energized. Because of experimental difficulties, the structure of the E…
Electron-Scale Dynamics of the Diffusion Region during Symmetric Magnetic Reconnection in Space
R. B. Torbert, J. L. Burch, T. D. Phan +46
Magnetic reconnection is an energy conversion process important in many astrophysical contexts including the Earth's magnetosphere, where the process can be investigated in-situ. H…
Generation of Electron Whistler Waves at the Mirror Mode Magnetic Holes: MMS Observations and PIC Simulation
Narges Ahmadi, Frederick Wilder, Robert Ergun +14
The Magnetospheric Multiscale (MMS) mission has observed electron whistler waves at the center and at the edges of magnetic holes in the dayside magnetosheath. The magnetic holes a…
Simulation of Observed Magnetic Holes in the Magnetosheath
Narges Ahmadi, Kai Germaschewski, Joachim Raeder
Magnetic holes have been frequently observed in the magnetosheath of Earth and it is believed that these structures are the result of nonlinear evolution of mirror instability. Mir…
Effects of electron temperature anisotropy on proton mirror instability evolution
Narges Ahmadi, Kai Germaschewski, Joachim Raeder
Proton mirror modes are large amplitude nonpropagating structures frequently observed in the magnetosheath. It has been suggested that electron temperature anisotropy can enhance t…
The Plasma Simulation Code: A modern particle-in-cell code with load-balancing and GPU support
Kai Germaschewski, William Fox, Stephen Abbott +5
Recent increases in supercomputing power, driven by the multi-core revolution and accelerators such as the IBM Cell processor, graphics processing units (GPUs) and Intel's Many Int…
p-species integrable reaction-diffusion processes
M. Alimohammadi, N. Ahmadi
We consider a process in which there are p-species of particles, i.e. A_1,A_2,...,A_p, on an infinite one-dimensional lattice. Each particle can diffuse to its right neighbor…
