Exact Master Equation and Quantum Decoherence of Two Coupled Harmonic Oscillators in a General Environment [PDF]

open access: yes, 2007
In this paper we derive an exact master equation for two coupled quantum harmonic oscillators interacting via bilinear coupling with a common environment at arbitrary temperature made up of many harmonic oscillators with a general spectral density ...

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

open access: yesQuantum 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.

Exact diagonalization of the D-dimensional spatially confined quantum harmonic oscillator [PDF]

open access: yesKragujevac Journal of Science, 2016
In the existing literature various numerical techniques have been developed to quantize the confined harmonic oscillator in higher dimensions. In obtaining the energy eigenvalues, such methods often involve indirect approaches such as searching for the ...

Rational extensions of the quantum harmonic oscillator and exceptional Hermite polynomials [PDF]

open access: yes, 2013
We prove that every rational extension of the quantum harmonic oscillator that is exactly solvable by polynomials is monodromy free, and therefore can be obtained by applying a finite number of state-deleting Darboux transformations on the harmonic ...

First harmonic injection locking of 24-GHz-oscillators [PDF]

open access: yesAdvances in Radio Science, 2003
An increasing number of applications is proposed for the 24 GHz ISM-band, like automotive radar systems and short-range communication links. These applications demand for oscillators providing moderate output power of a few mW and moderate frequency ...

Nodal Sets of Random Eigenfunctions for the Isotropic Harmonic Oscillator [PDF]

open access: yes, 2013
The expected hypersurface measure H(ZE,h ∩B(r, x)) of nodal sets of random eigenfunctions of eigenvalue E of the semi-classical isotropic harmonic oscillator in balls B(r, x) ⊂ R is determined as h → 0. In the allowed region the volumes are of order h−1,

Heat and work fluctuations for a harmonic oscillator. [PDF]

open access: yesPhysical review. E, Statistical, nonlinear, and soft matter physics, 2012
The formalism of Kundu et al. [J. Stat. Mech. P03007 (2011)], for computing the large deviations of heat flow in harmonic systems, is applied to the case of single Brownian particle in a harmonic trap and coupled to two heat baths at different ...

Simulation of harmonic oscillators on the lattice [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2020
This work deals with the simulation of a two‐dimensional ideal lattice having simple tetragonal geometry. The harmonic character of the oscillators give rise to a system of second‐order linear differential equations, which can be recast into matrix form. The explicit solutions which govern the dynamics of this system can be expressed in terms of matrix
