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.

Laser-induced, blackbody-radiation-assisted rovibrational cooling of symmetric-top molecular ions: NH3+ and ND3+

This theoretical study proposes a blackbody-radiation-assisted laser cooling scheme for symmetric-top molecular ions (NH3+ and ND3+) that achieves high ground-state population via the umbrella-bending mode at room temperature, while noting that low-temperature environments effectively freeze the population distribution by suppressing radiative redistribution.

Designing the Haystack: Programmable Chemical Space for Generative Molecular Discovery

The paper introduces SpaceGFN, a generative framework that transforms chemical space into a programmable object by decoupling the explicit construction of synthetically coherent molecular universes from GFlowNet-based exploration, thereby enabling both targeted discovery of novel scaffolds and synthesis-aware lead optimization.

General linear correction method for DFT+X energy: application to U-M (M=Al, Ga, In) alloys under high pressure

This paper proposes and validates a general linear correction method that resolves the intrinsic energy ambiguity in DFT+X approaches, thereby establishing them as fully first-principles tools capable of accurately predicting phase stability and discovering new intermetallic compounds in uranium-based alloys and other diverse systems under high pressure.

Competing adsorption of H and CO on Pd-alloy surfaces: Mechanistic insight into the mitigating effect of Cu on CO poisoning

This study employs a machine-learning-enhanced computational framework to reveal that while Au-rich Pd-Au-Cu surfaces suppress adsorption overall, the specific mitigation of CO poisoning by Cu arises from its ability to provide viable pathways for hydrogen absorption into the material when Pd-dominated paths are blocked.

Towards an understanding of magnesium in a biological environment: A density functional theory study

Using density functional theory, this study investigates the interactions between magnesium surfaces, magnesium hydroxide layers, and specific amino acids to reveal that the hydroxide layer binds weakly to the metal surface and that bulk formation becomes energetically favorable after only a few layers, offering insights into the early-stage corrosion behavior of biodegradable magnesium implants.

A Relationship between the Molecular Parity-Violation Energy and the Electronic Chirality Measure

This study establishes a strong positive correlation between the electronic chirality measure (ECM) and parity-violation energy differences (ΔEPV\Delta E_{PV}) in chiral molecules, suggesting that fundamental weak-force interactions may have imprinted a chiral signature on life and guiding future experimental detection efforts toward molecules with high ECM values.

Correction scheme for total energy obtained on fault-tolerant quantum computer via quantum dominant orbital selection and subspace dynamical correlation methods

This paper proposes a hybrid quantum-classical scheme utilizing quantum dominant orbital selection (QDOS) and subspace dynamical correlation (SDC) to accurately evaluate molecular energies on fault-tolerant quantum computers while avoiding the computational bottleneck of extracting full wavefunction data.
