Ground-state isolation and discrete flows in a rationally extended quantum harmonic oscillator [PDF]

, 2016
Ladder operators for the simplest version of a rationally extended quantum harmonic oscillator (REQHO) are constructed by applying a Darboux transformation to the quantum harmonic oscillator system.

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,

Radiation reaction and quantum damped harmonic oscillator

, 2005
By taking a Klein-Gordon field as the environment of an harmonic oscillator and using a new method for dealing with quantum dissipative systems (minimal coupling method), the quantum dynamics and radiation reaction for a quantum damped harmonic ...

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.

Discretized representations of harmonic variables by bilateral Jacobi operators

Discrete Dynamics in Nature and Society, 2000
Starting from a discrete Heisenberg algebra we solve several representation problems for a discretized quantum oscillator in a weighted sequence space. The Schrödinger operator for a discrete harmonic oscillator is derived. The representation problem for

Irreversible quantum graphs

, 2003
Irreversibility is introduced to quantum graphs by coupling the graphs to a bath of harmonic oscillators. The interaction which is linear in the harmonic oscillator amplitudes is localized at the vertices.

Well-posedness and convergence of the Lindblad master equation for a quantum harmonic oscillator with multi-photon drive and damping [PDF]

, 2015
We consider the model of a quantum harmonic oscillator governed by a Lindblad master equation where the typical drive and loss channels are multi-photon processes instead of single-photon ones; this implies a dissipation operator of order 2k with integer

Quantum harmonic oscillator state synthesis by reservoir engineering [PDF]

Science, 2014
Engineering a shelter for quantum protection In isolation, quantum states of matter can be stable entities. These states are often seen as useful when they can be made to interact in a controlled way.

Asymmetric variation of a finite mass harmonic like oscillator

Results in Physics, 2020
Classical and quantum mechanical analysis have been carried out on harmonic like oscillator with asymmetric position dependent mass. Phase space analysis are performed both classically and quantum mechanically for a plausible understanding of the subject.
