QED in vacuum can be approximated by the HE Lagrangian67,68, as expressed below in Gaussian units:
$${{{\mathcal{L}}}}=\frac{1}{8{{{\rm{\pi }}}}}\left({E}^{2}-{B}^{2}\right)+\frac{\xi }{8\pi…

To rigorously evaluate the efficacy of our novel CWT-DSCNN-CBAM framework, we established comprehensive simulation models incorporating three distinct active filter topologies: (i) Sallen–Key bandpass filter…
Physicists from the Muon g-2 experiment have released their third measurement of the muon magnetic anomaly. The final result agrees with their published results from 2021 and 2023 but with a much better precision of 127 parts-per-billion,…
The Big Bang is often described as the explosive birth of the Universe – a singular moment when space, time and matter sprang into existence.
But what if this was not the beginning at all? What if our Universe emerged from something else…
Physicists at Fermilab have made the most precise measurement ever of a long-disputed value – the magnetic ‘wiggle’ of an elementary particle known as a muon.
In somewhat disappointing news, that measurement is in strong agreement with the

A new framework for studying chiral materials puts the emphasis on electron chirality rather than on the asymmetry of the…

High-precision spectroscopy of weakly bound rubidium dimers pushes a theoretical model to its limits.
A Rydberg atom is one with a highly excited electron, and this electron can interact with a second…
The SVIRS epidemic model is defined by the following differential equations17:
$$\dot{S}=-\frac{\beta }{N}SI-\nu S+\eta V+\zeta R$$

$$\dot{V}=\nu S-\sigma \frac{\beta…
The optical setup of the quantum memory array is illustrated in Fig. 1a. Two optical fibers guide light for the preparation and control pulses as well as the memory input to the experimental setup. Four acousto-optic…
