This collection explores the fascinating intersection where the laws of physics meet the complex machinery of chemistry. Here, researchers investigate how quantum mechanics governs molecular bonds, how light interacts with matter at the atomic scale, and how fundamental forces shape chemical reactions. It is a realm where abstract mathematical models collide with tangible substances to reveal the hidden mechanisms driving our material world.

On Gist.Science, we process every new preprint in this category directly from arXiv to make these discoveries accessible to everyone. Whether you are a seasoned expert or a curious reader, you will find both plain-language explanations and detailed technical summaries for each paper. Below are the latest contributions from the community pushing the boundaries of physical chemistry.

Chemically Motivated Simulation Problems are Efficiently Solvable by a Quantum Computer

This paper proposes a heuristically guided, polynomially scalable quantum approach that utilizes scattering-based state preparation, specifically within the context of mergo-association, to efficiently solve chemical simulation problems by generating good initial states for dynamics simulations.

A finite element solver for a thermodynamically consistent electrolyte model

This paper presents a thermodynamically consistent, finite element-based electrolyte solver implemented in FEniCSx that accurately models multicomponent ionic transport by incorporating steric effects, solvation, and pressure coupling, thereby improving physical fidelity and numerical stability over classical frameworks for high-concentration electrochemical systems.

Near-surface Defects Break Symmetry in Water Adsorption on CeO2x_{2-x}(111)

By combining atomic force microscopy with first-principles calculations, this study reveals that subsurface defects in partially reduced CeO2x_{2-x}(111) break symmetry to dictate the asymmetric orientation of adsorbed water molecules, thereby identifying specific Ce3+^{3+} sites as thermodynamically favored centers for catalytic reactivity.

Semiclassical Spin Exchange via Temperature-Dependent Transition States

This paper introduces a first-principles semiclassical transition-state theory that successfully describes temperature-dependent spin-exchange collisions between 3^3He and 23^{23}Na by revealing a mechanism driven by a compromise between activation energy and hyperfine coupling, offering a computationally efficient alternative to traditional quantum-mechanical scattering methods.

Locally Scaled Self-Interaction Corrected Energy Functionals with Complex Optimal Orbitals

This paper presents a fully variational locally scaled self-interaction corrected energy functional that utilizes complex optimal orbitals and a kinetic energy density-based scaling factor to dynamically adjust the correction across different electron density regimes, thereby improving predictions for atomic, molecular, and solid-state systems.
