Quantum Damped Harmonic Oscillator [PDF]

open access: yes, 2012
In this chapter we treat the quantum damped harmonic oscillator, and study mathematical structure of the model, and construct general solution with any initial condition, and give a quantum counterpart in the case of taking coherent state as an initial ...

Quantum Harmonic Oscillator Spectrum Analyzers. [PDF]

open access: yesPhys Rev Lett, 2021
Characterization and suppression of noise are essential for the control of harmonic oscillators in the quantum regime. We measure the noise spectrum of a quantum harmonic oscillator from low frequency to near the oscillator resonance by sensing its response to amplitude modulated periodic drives with a qubit.

Quadratic open quantum harmonic oscillator [PDF]

open access: greenLetters in Mathematical Physics, 2020
We study the quantum open system evolution described by a Gorini-Kossakowski-Sudarshan-Lindblad generator with creation and annihilation operators arising in Fock representations of the $sl_2$ Lie algebra. We show that any initial density matrix evolves to a fully supported density matrix and converges towards a unique equilibrium state.

Comparison of Harmonic Oscillator Model in Classical and Quantum Theories of Light-Matter Interaction

open access: yesFoundations, 2023
A brief review of the classical and quantum description of the interaction of electromagnetic radiation with matter based on the model of a harmonic oscillator is presented.

Enhancement of quantum synchronization via continuous measurement and feedback control

open access: yesNew Journal of Physics, 2021
We study synchronization of a quantum van der Pol oscillator with a harmonic drive and demonstrate that quantum synchronization can be enhanced by performing continuous homodyne measurement on an additional bath linearly coupled to the oscillator and ...

Super algebra and Harmonic Oscillator in Anti de Sitter space [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics, 2019
The harmonic oscillator in anti de Sitter space(AdS) is discussed. We consider the harmonic oscillator potential and then time independent Schrodinger equation in AdS space.

Rogue quantum harmonic oscillations [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2020
We show the existence and investigate the dynamics and statistics of rogue oscillations (standing waves) generated in the frame of the nonlinear quantum harmonic oscillator (NQHO). With this motivation, in this paper, we develop a split-step Fourier scheme for the computational analysis of NQHO.

The multi-faceted inverted harmonic oscillator: Chaos and complexity

open access: yesSciPost 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.
