Harmonic Oscillator SUSY Partners and Evolution Loops [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
Supersymmetric quantum mechanics is a powerful tool for generating exactly solvable potentials departing from a given initial one. If applied to the harmonic oscillator, a family of Hamiltonians ruled by polynomial Heisenberg algebras is obtained.

Van der Waals interactions in density functional theory by combining the quantum harmonic oscillator-model with localized Wannier functions [PDF]

open access: greenJournal of Chemical Physics, 2013
We present a new scheme to include the van der Waals (vdW) interactions in approximated Density Functional Theory (DFT) by combining the quantum harmonic oscillator model with the maximally localized Wannier function technique.

Quantum harmonic oscillator with superoscillating initial datum [PDF]

open access: green, 2014
In this paper, we study the evolution of superoscillating initial data for the quantum driven harmonic oscillator. Our main result shows that superoscillations are amplified by the harmonic potential and that the analytic solution develops a singularity ...

Rational extensions of the quantum harmonic oscillator and exceptional Hermite polynomials [PDF]

open access: green, 2013
We prove that every rational extension of the quantum harmonic oscillator that is exactly solvable by polynomials is monodromy free, and therefore can be obtained by applying a finite number of state-deleting Darboux transformations on the harmonic ...

Time-dependent quantum harmonic oscillator: a continuous route from adiabatic to sudden changes [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2020
In this work, we give a quantitative answer to the question: how sudden or how adiabatic is a frequency change in a quantum harmonic oscillator (HO)? We do that by studying the time evolution of a HO which is initially in its fundamental state and whose ...

Topological Effects of a Spiral Dislocation on Quantum Revivals

open access: yesUniverse, 2022
We analyse the influence of spiral dislocation topology on the revival time for the harmonic oscillator, for a particle confined to one-dimensional quantum ring, and a two-dimensional quantum ring. We first investigate the effects of a cut-off point that

Algebraic solution for the classical harmonic oscillator

open access: yesRevista Brasileira de Ensino de Física, 2023
The harmonic oscillator is one of the most studied systems in Physics with a myriad of applications. One of the first problems solved in a Quantum Mechanics course is calculating the energy spectrum of the simple harmonic oscillator with analytic and ...

Quantum dynamics of A damped harmonic oscillator with velocity-dependent coupling [PDF]

open access: yesIranian Journal of Physics Research, 2022
The quantum theory of a damped harmonic oscillator has been continuously studied since 1939. For quantization, an oscillation oscillator usually uses a reservoir that includes a number of finite and discrete oscillators.
