They discovered an exact solution for a model that functions as a “damped quantum harmonic oscillator,” a quantum-scale version of a guitar string’s motion. It turns out that for roughly 90 years, ...

Multi-scale Quantum Harmonic Oscillator Algorith-m (MQHOA) is a recently proposed metaheuristic algorithm (MA), which simulates the photoelectron moves from high energy level down to the ground energy ...

In work published in Physical Review Research, they present an exact solution for what they call a “damped quantum harmonic oscillator,” essentially the atomic-scale equivalent of a slowly ...

It turns out that for roughly 90 years, theorists have tried to describe these damped harmonic systems using quantum physics—but with limited success.

This paper proposes a novel adaptive multi-scale quantum harmonic oscillator algorithm based on evolutionary strategies (AMQHOA-ES) for global numerical optimization. Since the original Multi-scale ...

A plucked guitar string can vibrate for seconds before falling silent. A playground swing, emptied of its passenger, will gradually come to rest. These are what physicists call "damped harmonic ...
