Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

SOLUTION OF HARMONIC OSCILLATOR OF NONLINEAR MASTER SCHRÖDINGER

Jurnal Fisika, 2012
We have computed the solution of a nonrelativistic particle motion in a harmonic oscillator potential of the nonlinear master Schrödinger equation. The equation itself is based on two classical conservation laws, the Hamilton-Jacobi and the continuity ...

Geometric quantum complexity of bosonic oscillator systems

Journal of High Energy Physics
According to the pioneering work of Nielsen and collaborators, the length of the minimal geodesic in a geometric realization of a suitable operator space provides a measure of the quantum complexity of an operation.

Comprehensive Modeling of Acetone Clusters: QTAIM Analysis and QCE Study

Journal of Computational Chemistry, Volume 47, Issue 11, 30 April 2026.
A multiscale DFT‐QTAIM‐QCE approach links acetone cluster interactions to liquid‐phase behavior. Macroscopic thermodynamic and IR properties emerge from a dynamic equilibrium of small clusters. ABSTRACT In molecular research, comprehending the microscopic source of the macroscopic characteristics of polar aprotic solvents continues to be a significant ...

Hierarchic superradiant phases in anisotropic Dicke model

SciPost Physics Core
We revisit the phase diagram of an anisotropic Dicke model by revealing the non-analyticity induced by underlying exceptional points. We find that, from a dynamical perspective, the conventional superradiant phase can be further separated into three ...

Transient Absorption Spectroscopy of Blue Copper Sites in Divergent Protein Folds: Azurin Versus Multicopper Oxidase

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Ultrafast pump‐probe spectroscopy of two evolutionarily divergent blue copper proteins reveals distinct low‐frequency ground‐state collective modes (38 cm−1 in SLAC, 29 cm−1 in azurin) generated via impulsive stimulated Raman scattering, potentially reflecting the differences in the rigidity of the surrounding protein scaffold beyond a conserved Cu ...

Structure and Dynamics of Imidazolium in an Ionic Liquid‐PEGDA Iongel via IR, 2D‐IR, and NMR Spectroscopy

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
Linear and nonlinear vibrational spectroscopies detect tight and loose complexes between imidazolium cations and poly(ethyleneoxide) chains in an iongel. Fourier transform infrared absorption spectroscopy, ultrafast two‐dimensional infrared spectroscopy, nuclear magnetic resonance spectroscopy, and density functional theory calculations show that, in ...

From the Modeling of Experiments to the Ab Initio Prediction of Rate Constants: Statistical Rate Theory for a Quantitative Understanding of Gas‐Phase Ion Chemistry

ChemPhysChem, Volume 27, Issue 8, 28 April 2026.
For directly comparing experimental results on gas‐phase ion reactions with the predictions from quantum chemical calculations, the latter must first be converted into rate constants. This review addresses the question of whether current methods of statistical rate theory can accomplish this task reliably. Statistical rate theory has long been used for
