On the photon–classical electromagnetic field relationship

Annals of the New York Academy of Sciences, Volume 1549, Issue 1, Page 11-21, July 2025.
Abstract This paper discusses how the two ways in which the wavefunction of a free‐propagating photon can be introduced—starting from the relativistic energy−momentum relationship or based on the electromagnetic field, in particular on Riemann–Silberstein vectors—are not entirely equivalent since they can lead to different consequences regarding photon

The effects of Majorana phases in three-generation neutrinos

, 2000
Neutrino-oscillation solutions for the atmospheric neutrino anomaly and the solar neutrino deficit can determine the texture of the neutrino mass matrix according to three types of neutrino mass hierarchies as Type A: $m_1^{} \ll m_2^{} \ll m_3 ...

Human‐AI Co‐Creativity: Does ChatGPT Make Us More Creative?

The Journal of Creative Behavior, Volume 59, Issue 2, June 2025.
ABSTRACT Much has been made of the apparent capacity for creativity of generative AI. However, as research expands the knowledge base regarding the capabilities and performance of this technology, the prevailing view is shifting away from “AI is creative” and towards a more balanced model of Human‐AI co‐creativity.

Nonequilibrium Neutrino Oscillations in the Early Universe with an Inverted Neutrino-Mass Hierarchy

, 1996
The annihilation of electron-positron pairs around one second after the big bang distorts the Fermi-Dirac spectrum of neutrino energies. We determine the distortions assuming neutrino mixing with an inverted neutrino-mass hierarchy.

Multi‐Source Forecast of Solar Cycle Flare Activity Using the Novel Informer‐Based Models

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Solar flares, the significant indicators of solar activity, have an impact on Earth's satellites and communication systems. Accurate prediction of solar flare events is crucial for mitigating these effects. In this work, we use multiple data sources, including Geostationary Operational Environmental Satellites soft X‐ray flare flux and the ...

Neutrino masses and bimaximal mixing [PDF]

Physics Letters B, 1999
Solar and atmospheric neutrino anomalies are described by bimaximal mixing of three neutrinos. Neutrino oscillations in appearance nu_e nu_mu,nu_tau and in disappearance nu_e long baseline and atmospheric experiments are sensitive to deviations from the ideal bimaximal mixing.

Current and future neutrino oscillation constraints on leptonic unitarity

Journal of High Energy Physics, 2020
The unitarity of the lepton mixing matrix is a critical assumption underlying the standard neutrino-mixing paradigm. However, many models seeking to explain the as-yet-unknown origin of neutrino masses predict deviations from unitarity in the mixing of ...

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...
