, 2006 The inverted harmonic oscillator problem is investigated quantum mechanically. The exact wave function for the confined inverted oscillator is obtained and it is shown that the associated energy eigenvalues are discrete and it is given as a linear ...

Quantum ReportsWe 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.

Nuclear Physics B, 2022 We show the emergence of Berry phase in a forced harmonic oscillator system placed in the quantum space-time of Moyal type, where the time ‘t’ is also an operator.

, 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.

Controllability of Quantum Harmonic Oscillators [PDF]
IEEE Transactions on Automatic Control, 2004 It is proven in a previous paper that any modal approximation of the one-dimensional quantum harmonic oscillator is controllable. We prove here that, contrary to such finite-dimensional approximations, the original infinite-dimensional system is not controllable: Its controllable part is of dimension 2 and corresponds to the dynamics of the average ...

Continuous-time quantum harmonic oscillator state engineering
New Journal of Physics, 2023 The center of mass motion of trapped ions and neutral atoms is suitable for approximation by a time-dependent driven quantum harmonic oscillator whose frequency and driving strength may be controlled with high precision.

Quantum parameter estimation of the frequency and damping of a harmonic oscillator [PDF]
, 2019 We determine the quantum Cramer-Rao bound for the precision with which the oscillator frequency and damping constant of a damped quantum harmonic oscillator in an arbitrary Gaussian state can be estimated.

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.

The Quantum Harmonic Oscillator in the ESR Model [PDF]
Foundations of Physics, 2013 The ESR model proposes a new theoretical perspective which incorporates the mathematical formalism of standard (Hilbert space) quantum mechanics (QM) in a noncontextual framework, reinterpreting quantum probabilities as conditional on detection instead of absolute.
