Code-Verification Techniques for Particle-in-Cell Simulations with Direct Simulation Monte Carlo Collisions
Brian A. Freno, William J. McDoniel, Christopher H. Moore +1
Particle-in-cell methods with stochastic collision models are commonly used to simulate collisional plasma dynamics, with applications ranging from hypersonic flight to semiconduct…
Reinforcement learning framework for the mechanical design of microelectronic components under multiphysics constraints
Siddharth Nair, Timothy F. Walsh, Greg Pickrell +1
This study focuses on the development of reinforcement learning based techniques for the design of microelectronic components under multiphysics constraints. While traditional desi…
Code-Verification Techniques for an Arbitrary-Depth Electromagnetic Slot Model
Brian A. Freno, Neil R. Matula, Robert A. Pfeiffer +1
Electromagnetic slot models are employed to efficiently simulate electromagnetic penetration through openings in an otherwise closed electromagnetic scatterer. Such models, which i…
Manufactured Solutions for an Electromagnetic Slot Model
Brian A. Freno, Neil R. Matula, Robert A. Pfeiffer +2
The accurate modeling of electromagnetic penetration is an important topic in computational electromagnetics. Electromagnetic penetration occurs through intentional or inadvertent…
First principles simulations of dense hydrogen
Michael Bonitz, Jan Vorberger, Mandy Bethkenhagen +24
Accurate knowledge of the properties of hydrogen at high compression is crucial for astrophysics (e.g. planetary and stellar interiors, brown dwarfs, atmosphere of compact stars) a…
Breaking the Molecular Dynamics Timescale Barrier Using a Wafer-Scale System
Kylee Santos, Stan Moore, Tomas Oppelstrup +11
Molecular dynamics (MD) simulations have transformed our understanding of the nanoscale, driving breakthroughs in materials science, computational chemistry, and several other fiel…
