The driven damped quantum harmonic oscillator perturbed by the parity operator, is studied in the framework of the reduced density operator formalism. Benefit is taken of the closed approach of Louisell and Walker to find the dynamics of the system. The starting point is the reduced density ...
Damped Harmonic Oscillator Wednesday, 23 October 2013 A simple harmonic oscillator subject to linear damping may oscillate with exponential decay, or it may decay bi- exponentially without oscillating, or it may decay most rapidly when it is critically damped. When driven sinu- soidally, it resonat...
By virtue of the entangled-state basis and the ket-vector representation of the density operator, we solve the master equation of a driven damped harmonic oscillator. In this representation, the density operators are mapped to vectors of a two-mode Fock space whose first mode is the system mod...

Driven harmonic oscillator as a quantum simulator for open systems We show theoretically how a driven harmonic oscillator can be used as a quantum simulator for non-Markovian damped harmonic oscillator. In the general fram... J Piilo,S Maniscalco - 《Physical Review A Atomic Molecular & Optical...
In this study, we calculate the torque induced on a plasmonic nanocuboid by modelling the surface plasmon resonance (SPR) as a driven damped harmonic oscillator. Using numerical simulations, we demonstrate the model's accuracy in predicting the torque induced for narrow nanocuboids. We also ...

One cannot directly access the quantum states themselves but only transitions between them. Various methods bring ...
