Fingerprints of the quantum space-time in time-dependent quantum mechanics: An emergent geometric phase

open access: yesNuclear Physics B, 2022
We show the emergence of Berry phase in a forced harmonic oscillator system placed in the quantum space-time of Moyal type, where the time ‘t’ is also an operator.

Relativistic harmonic oscillator [PDF]

open access: yesJournal of Mathematical Physics, 2005
We study the semirelativistic Hamiltonian operator composed of the relativistic kinetic energy and a static harmonic-oscillator potential in three spatial dimensions and construct, for bound states with vanishing orbital angular momentum, its eigenfunctions in “compact form,” i.e., as power series, with expansion coefficients determined by an ...

Spiked harmonic oscillators [PDF]

open access: yesJournal of Mathematical Physics, 2002
A complete variational treatment is provided for a family of spiked-harmonic oscillator Hamiltonians H=−d2/dx2+Bx2+λ/xα(B>0,λ>0), for arbitrary α>0. A compact topological proof is presented that the set S={ψn} of known exact solutions for α=2 constitutes an orthonormal basis of the Hilbert space L2(0,∞). Closed-form expressions are

On the Inverse to the Harmonic Oscillator [PDF]

open access: yesCommunications in Partial Differential Equations, 2015
Let $b_d$ be the Weyl symbol of the inverse to the harmonic oscillator on $\R^d$. We prove that $b_d$ and its derivatives satisfy convenient bounds of Gevrey and Gelfand-Shilov type, and obtain explicit expressions for $b_d$. In the even-dimensional case we characterize $b_d$ in terms of elementary functions. In the analysis we use properties of radial

Approximate Solution of Schrodinger Equation to Diatomic Molecule for Harmonic Oscillator

open access: yesUMYU Scientifica Journal, 2023
This study has described the approximate solution of Schrodinger equation to diatomic molecule for harmonic oscillator. The solution procedure is developed by the Power series method and Newton’s second law.

Global residue harmonic balance method for strongly nonlinear oscillator with cubic and harmonic restoring force

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2022
This paper focuses on the numerical investigation of a strongly nonlinear oscillator with cubic and harmonic restoring force. We transform this oscillator as a free damped cubic-quintic Duffing oscillator equation by Taylor approximation.

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

Photonic microwave harmonic generator driven by an optoelectronic ring oscillator [PDF]

open access: yes, 2007
We describe a new architecture to generate microwave signals by optical means. Our system combines the advantages of two techniques: frequency multipliers and loop oscillators.
