Open-Source Workflows for Reproducible Molecular Simulation
We apply molecular simulation to predict the equilibrium structure of organic molecular aggregates and how these structures determine material properties, with a focus on software engineering practices for ensuring correctness. Because simulations are implemented in software, there is potential for authentic scientific reproducibility in such work: An entire experimental apparatus (codebase) can be given to another investigator who should be able to use the same processes to find the same answers. Yet in practice, there are many barriers which stand in the way of reproducible molecular simulations that we address through automation, generalization, and software packaging. Collaboration on and application of the Molecular Simulation and Design Framework (MoSDeF) features prominently.
We present structural investigations of organic molecule aggregates and the development of infrastructure and workflows that help manage, initialize, and analyze molecular simulation results through the following scientific applications (1) A screening study wherein we validate self-assembled poly-3-hexylthiophene (P3HT) morphologies show the same state dependency as in prior work, and (2) A multi-university collaborative reproducibility study where we examine modeling choices that give rise to differences between simulation engines. In aggregate, we reinforce the need for pipelines and practices emphasizing transferability, reproducibility, useability, and extensibility in molecular simulation
Quantum Simulation for High Energy Physics
It is for the first time that Quantum Simulation for High Energy Physics
(HEP) is studied in the U.S. decadal particle-physics community planning, and
in fact until recently, this was not considered a mainstream topic in the
community. This fact speaks of a remarkable rate of growth of this subfield
over the past few years, stimulated by the impressive advancements in Quantum
Information Sciences (QIS) and associated technologies over the past decade,
and the significant investment in this area by the government and private
sectors in the U.S. and other countries. High-energy physicists have quickly
identified problems of importance to our understanding of nature at the most
fundamental level, from tiniest distances to cosmological extents, that are
intractable with classical computers but may benefit from quantum advantage.
They have initiated, and continue to carry out, a vigorous program in theory,
algorithm, and hardware co-design for simulations of relevance to the HEP
mission. This community whitepaper is an attempt to bring this exciting and yet
challenging area of research to the spotlight, and to elaborate on what the
promises, requirements, challenges, and potential solutions are over the next
decade and beyond.Comment: This is a whitepaper prepared for the topical groups CompF6 (Quantum
computing), TF05 (Lattice Gauge Theory), and TF10 (Quantum Information
Science) within the Computational Frontier and Theory Frontier of the U.S.
