A Method Based on a Nonlinear Generalized Heisenberg Algebra to Study the Molecular Vibrational Spectrum

We propose a method, based on a Generalized Heisenberg Algebra (GHA), to reproduce the anharmonic spectrum of diatomic molecules. The theoretical spectrum generated by GHA allows us to fit the experimental data and to obtain the dissociation energy for the carbon monoxide molecule. Our outcomes are more accurate than the standard models used to study molecular vibrations, namely the Morse and the $q$-oscillator models and comparable to the perturbed Morse model proposed by Huffaker \cite{hf}, for the first experimental levels. The dissociation energy obtained here is more accurate than all previous models.

Generalized Quantum Field Theory as an Alternative Approach To The Problem of Composite Particles Reaction

A generalization of the Heisenberg algebra has been recently constructed. This generalized algebra has a characteristic function which depends on one of its generators. When this function is linear, $qJ_0+s$, it is possible to construct a Generalized Quantum Field Theory (GQFT) that creates at a space-time a composite particle.In the present work we show that a generalized QFT can also be constructed consistently, even with a nonlinear characteristic function and leads to better results as long as we have more parameters to (possibly) fit the spectrum of a real composite particle.
