From Molecules to Bioaggregates: Unraveling the Photoexcitation Dynamics of Intracellularly Self‐Assembled Thiophene‐Based Fibers

Small Science, EarlyView.
Cell‐guided self‐assembly of thiophene based molecules inside living cells produces photostable, biocompatible nanofibers exhibiting J‐like excitonic coupling and stimulated emission. Integrated spectroscopic and quantum‐chemical analyses reveal unique photophysical behavior and low phototoxicity, positioning these supramolecular structures as ...

Power of the Many‐Body Force: Magnitudes and Angles of Atomic Van der Waals Dispersion Forces in Extended Molecular Systems

Small Structures, EarlyView.
Many‐body dispersion (MBD) forces are stronger, longer‐ranged, and more accurate than pairwise van der Waals (vdW) models. By comparing polyethylene melts, benzene solutions, and fullerenes, it is shown that a slower‐decay corrected pairwise scheme can recover MBD magnitudes.

Quantum Limits for Harmonic Oscillator

, 2019
In this note we consider high energy eigenfunctions of the harmonic oscillator in $\mathbb{R}^d$ and prove that any invariant measure on the energy surface can be written as a weak limit of eigenfunctions.

Molecular Excitons and Plasmons in Acenes and Their Radical Cations

Journal of Computational Chemistry, Volume 46, Issue 23, 05 September 2025.
The electronic structure and the physical character of the energetically low‐lying excited electronic states determine the applicability of acenes and their radical cations in organic electronics. Here we employ the intuitive picture of molecular excitons and plasmons to classify these states and their properties with increasing lengths of the acenes ...

Theoretical Kinetics Study of the OH + CH3SH Reaction Based on an Analytical Full‐Dimensional Potential Energy Surface

International Journal of Chemical Kinetics, Volume 57, Issue 9, Page 520-529, September 2025.
ABSTRACT Based on a recently developed full‐dimensional analytical potential energy surface, named PES‐2024, which was fitted to high‐level ab initio calculations, three different kinetic theories were used for the computation of thermal rate constants: variational transition state theory (VTST), quasi‐classical trajectory theory (QCT) and ring polymer

The modified airy function approximation applied to the double-well potential

AIP Advances
The single harmonic oscillator and double-well potentials are important systems in quantum mechanics. The single harmonic oscillator is the paradigm in physics and is taught in nearly all beginner undergraduate classes, while the double-well potential ...
