Subnormality in the Quantum Harmonic Oscillator

, 2007
. This is an invitation to enjoy watching how unbounded subnormality, a rather recent development, gets involved in solving the commutation relation of the quantum harmonic oscillator. 1991 Mathematics Subject Classification.

Complexity study of q-deformed quantum harmonic oscillator

, 2019
The statistical complexity measure defined by Lopez-Ruiz, Mancini, and Calbet is reported for a single particle under q-deformed quantum harmonic oscillator. It is found that q-deformation leads to typically a different behavior in complexity.

NTECARS: A Nonthermal Equilibrium CARS Spectra Fitting Code

Journal of Raman Spectroscopy, EarlyView.
We present NTECARS, an open‐source code written in Julia for the calculation and fitting of CARS spectra under nonequilibrium conditions. Rovibrational distributions can be flexibly modeled and fitted for different use cases. The code currently implements CO2$$ \mathrm{C}{\mathrm{O}}_2 $$ and N2$$ {\mathrm{N}}_2 $$ molecules and is validated under ...

Quantum resonances in the delta-kicked harmonic oscillator

, 2009
Under certain conditions, the quantum delta-kicked harmonic oscillator displays quantum resonances. We consider an atom-optical realization of the delta-kicked harmonic oscillator and present a theoretical discussion of the quantum resonances that could ...

Reaction Rate Coefficients and Adduct Formation in the Cl Atom + (E)‐CF3CF2CH=CHCF2CF3 Reaction

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT In this work, rate coefficients for the Cl‐atom + (E)‐CF3CF2CH═CHCF2CF3 (HFO‐153‐10mczz, F22E) gas‐phase reaction were measured as a function of temperature and pressure, k(243–323 K, 50–300 Torr), using a pulsed laser photolysis‐resonance fluorescence (PLP‐RF) technique.

On relativistic harmonic oscillator

, 2017
A relativistic quantum harmonic oscillator in 3+1 dimensions is derived from a quaternionic non-relativistic quantum harmonic oscillator. This quaternionic equation also yields the Klein-Gordon wave equation with a covariant (space-time dependent) mass ...

Coherent States of the Conformable Quantum Oscillator

Dynamics
The recently proposed conformable deformation of quantum mechanics by a fractional parameter α∈(0,1] has been used to construct a conformable quantum harmonic oscillator, which coincides with the standard quantum oscillator at α=1. We argue that there is

Size Matters: Barrier Heights and Widths in the Kinetics Of Tautomerisation and Rotamerisation of Thiotropolone and Its Five‐ and Three‐Membered Cyclic Analogues

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT Recent experiments by Nunes et al. have demonstrated that unprecedented control of chemical reactions is possible by narrowband infrared vibrational photo‐excitation at low temperatures in inert matrices. The generated higher energy level conformers may then undergo rotamerisation and tautomerisation reactions which provide extremely useful ...
