Numerical investigation of the fractal capillary oscillator

Journal of Low Frequency Noise, Vibration and Active Control, 2023
This paper focuses on the numerical investigation of a fractal modification of capillary oscillator by using a coupling technique based on the two-scale transformation and the global residue harmonic balance method.

Harmonic Oscillators in CMOS—A Tutorial Overview

IEEE Open Journal of the Solid-State Circuits Society, 2021
The harmonic oscillator is a truly irreplaceable as well as ubiquitous analog integrated circuit. Starting from the basics of its CMOS implementation, we will discuss the phase noise of the harmonic oscillator in some detail, where the intrinsic large ...

Simple Harmonic Oscillator Equation and Its Hyers-Ulam Stability

Journal of Function Spaces and Applications, 2012
We solve the inhomogeneous simple harmonic oscillator equation and apply this result to obtain a partial solution to the Hyers-Ulam stability problem for the simple harmonic oscillator equation.

The Harmonic Oscillator on the Heisenberg Group

Comptes Rendus. Mathématique, 2020
In this note we present a notion of harmonic oscillator on the Heisenberg group $\mathbf{H}_n$ which forms the natural analogue of the harmonic oscillator on $\mathbb{R}^n$ under a few reasonable assumptions: the harmonic oscillator on $\mathbf{H}_n ...

The multi-faceted inverted harmonic oscillator: Chaos and complexity

SciPost Physics Core, 2021
The harmonic oscillator is the paragon of physical models; conceptually and computationally simple, yet rich enough to teach us about physics on scales that span classical mechanics to quantum field theory.

Evolving Probability Representations of Entangled Cat States in the Potentials of Harmonic and Inverted Oscillators

Quantum Reports
We determine the evolving probability representation of entangled cat states in the potential of either the harmonic oscillator or the inverted oscillator, assuming that the states are initially prepared in the potential of the harmonic oscillator.

Quantum dynamics of the damped harmonic oscillator

New Journal of Physics, 2012
The quantum theory of the damped harmonic oscillator has been a subject of continual investigation since the 1930s. The obstacle to quantization created by the dissipation of energy is usually dealt with by including a discrete set of additional harmonic

Empirical Rules for Oscillation and Harmonic Approximation of Fractional Kelvin–Voigt Oscillators

Applied Sciences
Fractional Kelvin–Voigt (FKV) oscillators describe vibrations in viscoelastic structures with memory effects, leading to dynamics that are often more complex than those of classical harmonic oscillators.
