Clustering of Global Magnetospheric Observations
Journal of Geophysical Research: Machine Learning and Computation, Volume 1, Issue 4, December 2024.Abstract The use of supervised methods in space science have demonstrated powerful capability in classification tasks, but purely unsupervised methods have been less utilized for the classification of spacecraft observations. We use a combination of unsupervised methods, being principal component analysis, Self‐Organizing Maps, and hierarchical ...

Quantized Excitation Spectrum of the Classical Harmonic Oscillator in Zero-Point Radiation [PDF]
, 2012 We report that upon excitation by a single pulse, the classical harmonic oscillator immersed in classical electromagnetic zero-point radiation, as described by random electrodynamics, exhibits a quantized excitation spectrum in agreement to that of the ...

Quantum electrodynamic equations for magnetic resonance- and optical spectroscopic transitions [PDF]
arXiv, 2009 Quantum electrodynamic equations for magnetic resonance- and optical spectroscopic transitions have been for the first time obtained. New phenomena - stochastic electrical and magnetic spin wave resonances are predicted to be the effects of EM-field quantization.

Connecting two stochastic theories that lead to quantum mechanics [PDF]
arXiv, 2020 The connection is established between two theories that have developed independently with the aim to describe quantum mechanics as a stochastic process, namely stochastic quantum mechanics (sqm) and stochastic electrodynamics (sed). Important commonalities and complementarities between the two theories are identified, notwithstanding their dissimilar ...

Maxwell Electromagnetic Theory, Planck's Radiation Law and Bose-Einstein Statistics [PDF]
, 1995 We give an example in which it is possible to understand quantum statistics using classical concepts. This is done by studying the interaction of charged matter oscillators with the thermal and zeropoint electromagnetic fields characteristic of quantum electrodynamics and classical stochastic electrodynamics.

Quantum Mechanical Ground State of Hydrogen Obtained from Classical Electrodynamics [PDF]
, 2003 The behavior of a classical charged point particle under the influence of only a Coulombic binding potential and classical electromagnetic zero-point radiation, is shown to yield agreement with the probability density distribution of Schroedinger's wave equation for the ground state of hydrogen.

The Onset of Lasing in Semiconductor Nanolasers
Laser &Photonics Reviews, Volume 18, Issue 11, November 2024.Correct identification of the threshold of nanolasers requires the consideration of spontaneous emission quantum noise. A new definition, the laser threshold with photon recycling, is introduced and compared to definitions from the literature. The new definition covers the entire range from macroscopic lasers to nanolasers. Abstract Nanolasers based on

Continuous Wave Function Collapse in Quantum-Electrodynamics? [PDF]
, 2006 Time-continuous wavefunction collapse mechanisms n o t restricted to markovian approximation have been found only a few years ago, and have left many issues open. The results apply formally to the standard relativistic quantum-electrodynamics. I present a generalized Schrodinger equation driven by a certain complex stochastic field.
