Propagation, breathing and transition of matter-wave packet trains [PDF]
, 2003 We find a set of new exact solutions of a quantum harmonic oscillator, which describes some wave-packet trains with average energy being proportional to both the quantum level and classical energy of the oscillator.

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 ...

Advanced Materials, EarlyView.In the work reported herein, the catalytic effects of acid sites on electrocatalytic glycerol oxidation reaction are investigated by using a novel catalytic material system that integrates Pt metal sites with acidic Al sites. Abstract The catalytic role and function of acid sites in solid acid catalysts, such as zeolites, are well understood in the ...

Instanton solutions on the polymer harmonic oscillator
, 2016 It is computed, using instanton methods, the first allowed energy band for the polymer harmonic oscillator. The result is consistent with the band structure of the standard quantum pendulum but with pure point spectrum.

A Wigner distribution function for finite oscillator systems [PDF]
, 2013 We define a Wigner distribution function for a one-dimensional finite quantum system, in which the position and momentum operators have a finite (multiplicity-free) spectrum. The distribution function is thus defined on discrete phase-space, i.e.

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.

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.This study reveals the potential to manipulate spin‐valley polarization dynamics in MoSe2/WSe2 heterostructures by quantifying different scattering processes following selective photoexcitation. The results show that these heterostructures enable ultrafast valley‐selective charge transfer, with phonon scattering playing a significant role in the ...
