Conformal Transformation of the Schrödinger Equation for the Harmonic Oscillator into a Simpler Form [PDF]
arXiv, 2010 The Schr\"{o}dinger equation and ladder operators for the harmonic oscillator are shown to simplify through the use of an isometric conformal transformation. These results are discussed in relation to the Bargmann representation. It is further demonstrated that harmonic interactions can be introduced into quantum mechanics as an imaginary component of ...

A Combined Infrared Spectroscopy Database and Analysis Tool
Chemie Ingenieur Technik, EarlyView.Modern DFT software often lacks sufficient tooling to adjust for peak broadening effects in infrared spectroscopy. The described application approximates peak width using Gaussian functions, allowing for real‐time adjustments and comparisons with experimental and simulated spectra, in addition to a spectral database.

Symmetry, Integrability and Geometry: Methods and Applications, 2011 The Stäckel transform is applied to the geodesic motion on Euclidean space, through the harmonic oscillator and Kepler-Coloumb potentials, in order to obtain maximally superintegrable classical systems on N-dimensional Riemannian spaces of nonconstant ...

ChemMedChem, EarlyView.Novel pheophorbide A, a chlorophyll‐derived compound was prepared by simple and sustainable synthesis. Small structural change to known molecules has a profound effect on the PDT efficacy and its phototoxicity is substantially higher than reference compound m‐THPC.

ChemPhysChem, EarlyView.Temperature‐dependent time‐resolved photoluminescence (PL) and transient absorption spectroscopy track the generation and decay of two self‐trapped exciton states (STE1 and STE2) in an [N(C3H7)4]2[Cu4Br6] thin film after photoexcitation. This efficient zero‐dimensional halocuprate(I) emitter shows a quite rarely observed increase of the PL intensity ...

Star products and deformed oscillators [PDF]
arXiv, 1993 A star-product formalism describing deformations of the standard quantum mechanical harmonic oscillator is introduced. A number of existing generalized oscillators occur as particular choises of star-products between the elements of the ordinary oscillator algebra. Star dynamics and coherent states are introduced and studied.

Vibrational Partition Functions from Bond Order and Populations Relationships
ChemPhysChem, Accepted Article.We present a novel method that computes harmonic vibrational partition functions from bond orders and popu‐ lation relationships (QBOP). The QBOP model first computes ZPEs and net vibrational bond energies from our earlier zero‐point energies from bond orders and populations (ZPE‐BOP) model and then maps these variables to calculate the harmonic ...
