Quantum Signal Processing for Linear PDEs: Circuit Design and Experimental Validation
Hyeongjin Kim, Revathi Jambunathan, Jan Balewski +1
Quantum algorithms offer new avenues for solving partial differential equations (PDEs). While the potential for end-to-end quantum advantage is at present not well understood, rece…
Application of mesh refinement to relativistic magnetic reconnection
Revathi Jambunathan, Henry Jones, Lizzette Corrales +5
During relativistic magnetic reconnection, antiparallel magnetic fields undergo a rapid change in topology, releasing a large amount of energy in the form of non-thermal particle a…
Two-fluid Physical Modeling of Superconducting Resonators in the ARTEMIS Framework
Revathi Jambunathan, Zhi Yao, Richard Lombardini +2
In this work, we implement a new London equation module for superconductivity in the GPU-enabled ARTEMIS framework, and couple it to a finite-difference time-domain solver for Maxw…
Particle-in-Cell Simulations of Relativistic Magnetic Reconnection with Advanced Maxwell Solver Algorithms
Hannah Klion, Revathi Jambunathan, Michael E. Rowan +7
Relativistic magnetic reconnection is a non-ideal plasma process that is a source of non-thermal particle acceleration in many high-energy astrophysical systems. Particle-in-cell (…
From Compact Plasma Particle Sources to Advanced Accelerators with Modeling at Exascale
Axel Huebl, Remi Lehe, Edoardo Zoni +21
Developing complex, reliable advanced accelerators requires a coordinated, extensible, and comprehensive approach in modeling, from source to the end of beam lifetime. We present h…
FerroX : A GPU-accelerated, 3D Phase-Field Simulation Framework for Modeling Ferroelectric Devices
Prabhat Kumar, Andrew Nonaka, Revathi Jambunathan +3
We present a massively parallel, 3D phase-field simulation framework for modeling ferro-electric materials based scalable logic devices. We self-consistently solve the time-depende…
Characterization of Transmission Lines in Microelectronics Circuits using the ARTEMIS Solver
Saurabh S. Sawant, Zhi Yao, Revathi Jambunathan +1
Modeling and characterization of electromagnetic wave interactions with microelectronic devices to derive network parameters has been a widely used practice in the electronic indus…
Absorption of charged particles in Perfectly-Matched-Layers by optimal damping of the deposited current
Remi Lehe, Aurore Blelly, Lorenzo Giacomel +2
Perfectly-Matched Layers (PML) are widely used in Particle-In-Cell simulations, in order to absorb electromagnetic waves that propagate out of the simulation domain. However, when…
A Massively Parallel Time-Domain Coupled Electrodynamics-Micromagnetics Solver
Zhi Yao, Revathi Jambunathan, Yadong Zeng +1
We present a new, high-performance coupled electrodynamics-micromagnetics solver for full physical modeling of signals in microelectronic circuitry. The overall strategy couples a…
Porting WarpX to GPU-accelerated platforms
A. Myers, A. Almgren, L. D. Amorim +20
WarpX is a general purpose electromagnetic particle-in-cell code that was originally designed to run on many-core CPU architectures. We describe the strategy followed to allow Warp…
