THE COUPLING OF GRAVITY TO SPIN AND ELECTROMAGNETISM [PDF]
Modern Physics Letters A, 1999 The coupled Einstein–Dirac–Maxwell equations are considered for a static, spherically symmetric system of two fermions in a singlet spinor state. Stable soliton-like solutions are shown to exist, and we discuss the regularizing effect of gravity from a Feynman diagram point of view.

Analysis of the Main Interference Causes of Acoustoelectric Logging Detector
Cejing jishu, 2023 Acoustic-type logging instruments generate high voltages in the order of thousands of volts. Electromagnetic interferences are thus induced by high-voltage pulses that affect the logging tool and make it inoperable owing to damaged components in severe ...

COUPLING ELECTROMAGNETISM TO GLOBAL CHARGE [PDF]
International Journal of Modern Physics A, 2013 It is shown that an alternative to the standard scalar quantum electrodynamics (QED) is possible. In this new version, there is only global gauge invariance as far as the charged scalar fields are concerned, although local gauge invariance is kept for the electromagnetic field.

Electromagnetic Couplings of Axions
, 2022 We show that, contrary to assertions in the literature, the main contribution to the axion-photon coupling need not be quantized in the units proportional to $e^2$. In particular, we discuss a loophole in the argument for this quantization and then provide explicit counterexamples.
