An Interoperable Syntax for Gas Scattering Reaction Definition

We propose a unified, human-readable, machine-processable novel syntax/notation designed to comprehensively describe reactions, molecules and excitation states. Our notation resolves inconsistencies in existing data representations and facilitates seamless integration with computational tools. We define a structured syntax for molecular species, excitation states, and reaction mechanisms, ensuring compatibility with a wide range of scientific applications. We provide a reference implementation based on Parsing Expression Grammar syntax, enabling automated parsing and interpretation of the proposed notation. This work is available as an open-source project, enabling validation and fostering its adoption and further improvement by the scientific community. Our standardized framework provides gas scattering models with increased interoperability and accuracy.

A new advance on dimensional-aware scalar, vector and matrix operations in C++

We review the dimensional check problem of the high-level programming languages, discuss the existing solutions, and come up with a new solution suited for scientific and engineering computations. Then, we introduce Univec, our C++ library designed to make scalar, vector, and matrix operations using units of measurement. Moreover, Univec supports dimensional-aware operations for complex numbers, quaternions, octonions, and sedenions. We provide tables of the relevant functions and operators implemented. Our library was compared with several existing solutions, and the results are shown in the performance section. Finally, we present our future plans for improving the current implementation.

Betaboltz: a Monte-Carlo simulation tool for gas scattering processes

We present an open-source code for the simulation of electron and ion transport for user-defined gas mixtures with static uniform electric and magnetic fields. The program provides microscopic interaction simulation and is interfaced with cross-section tables published by LXCat[1]. The framework was validated against drift velocity tables available in literature obtaining an acceptable match for atomic and non-polar molecular gases with spherical symmetry. The code is written in C++17 and is available as a shared library for easy integration into other simulation applications.
