A quadratic time-dependent quantum harmonic oscillator. [PDF]
Sci Rep, 2023 We present a Lie algebraic approach to a Hamiltonian class covering driven, parametric quantum harmonic oscillators where the parameter set—mass, frequency, driving strength, and parametric pumping—is time-dependent.

Thermalization in a Quantum Harmonic Oscillator with Random Disorder. [PDF]
Entropy (Basel), 2020 We propose a possible scheme to study the thermalization in a quantum harmonic oscillator with random disorder. Our numerical simulation shows that through the effect of random disorder, the system can undergo a transition from an initial nonequilibrium ...

Quantum Harmonic Oscillator Spectrum Analyzers. [PDF]
Phys 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 ...

Multiscale Quantum Harmonic Oscillator Algorithm for Multimodal Optimization. [PDF]
Comput Intell Neurosci, 2018 This paper presents a variant of multiscale quantum harmonic oscillator algorithm for multimodal optimization named MQHOA-MMO. MQHOA-MMO has only two main iterative processes: quantum harmonic oscillator process and multiscale process.

Heat distribution of a quantum harmonic oscillator [PDF]
Physical Review E, 2018 We consider a thermal quantum harmonic oscillator weakly coupled to a heat bath at a different temperature. We analytically study the quantum heat exchange statistics between the two systems using the quantum-optical master equation.

A discrete quantum model of the harmonic oscillator [PDF]
Journal of Physics A: Mathematical and Theoretical, 2008 We construct a new model of the quantum oscillator, whose energy spectrum is equally-spaced and lower-bounded, whereas the spectra of position and momentum are a denumerable non-degenerate set of points in [-1,1] that depends on the deformation parameter q from (0,1). We provide its explicit wavefunctions, both in position and momentum representations,

Finite quantum kinematics of the harmonic oscillator [PDF]
Journal of Mathematical Physics, 2006 Arbitrarily small changes in the commutation relations suffice to transform the usual singular quantum theories into regular quantum theories. This process is an extension of canonical quantization that we call general quantization. Here we apply general quantization to the time-independent linear harmonic oscillator.
