Exponential Decay in Quantum Mechanics

2012
First of all: disregard all of so called "preliminary physical expectations", because all these expectations are just a pseudonym for prejudices elaborated by the older generation. These words belong to Dirac, not to me. The right way of creating new physics is different: one should begin with a beautiful mathematical idea.

Phosphorescence as an exponential decay

The Physics Teacher, 2021
Phosphorescence is always an engaging demonstration. A high-energy photon source, such as a violet laser or UV black light, shines on a phosphor (screen, mineral, toy, etc.) and then the light is reemitted slowly at a color of lower energy. We notice that the intensity of the emitted light dims with time.

Exponential Decay With a Memory

American Journal of Physics, 1972
We examine the exponential decay law for an excited quantum system in the case where the state amplitude has a “memory,” that is, where the rate at which the amplitude is decaying at a particular time depends to some extent on values of the amplitude at previous times.

Exponentially Decaying Explosion in Fireworks Algorithm

2021 IEEE Congress on Evolutionary Computation (CEC), 2021
Fireworks algorithm (FWA) as an efficient and robust swarm intelligence algorithm can successfully deal with complex multi-modal problems. In this paper, a novel new explosion operator called exponentially decaying explosion is proposed to enhance the local search ability of fireworks algorithm based on the principle of utilizing more information.

Exponential tooth decay curve.

Community dental health, 2019
A review of the distribution of d₃mft scores for Wales was undertaken to inform decisions on future reporting of decay experience. Visual examination of data from one survey suggested that caries in Wales is distributed along an exponential decay curve.Weighted d₃mft data from 2007/8, 2011/12 and 2014/15 was utilised.

On the identification of exponentially decaying signals

IEEE Transactions on Signal Processing, 1995
Studies a new approach to estimating the component amplitudes and decay rates of transient signals that consist of real decaying exponentials. A set of predetermined "basis" exponentials is fitted to discrete samples of a signal. The basis is required to be selective, each basis exponential "selecting" signal exponents that are close to its own and ...
