Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

Efforts to place limits on deviations from canonical formulations of electromagnetism and
gravity have probed length scales increasing dramatically over time. Historically, these …

The dark photon is a massive hypothetical particle that interacts with the Standard Model by
kinetically mixing with the visible photon. For small values of the mixing parameter, dark …

We investigate the instability of the massive scalar field in the vicinity of a rotating black hole.
The instability arises from amplification caused by the classical superradiance effect. The …

One hundred years ago Albert Einstein introduced the concept of the photon. Although in the
early years after 1905 the evidence for the quantum nature of light was not compelling …

The frequency-dependent time delays in fast radio bursts (FRBs) can be used to constrain
the photon mass, if the FRB redshifts are known, but the similarity between the frequency …

I was educated first as a geologist and then as a mathematician. For that reason my clash
with the actual infinity was devastating for my original scientific project (thermodynamics of …

In this work, we study the thermodynamic properties of a photon gas in a heat bath within the
context of higher-derivative electrodynamics. Specifically, we analyze Podolsky's theory and …

The photon mass, m γ, can in principle be constrained using measurements of the
dispersion measures (DMs) of fast radio bursts (FRBs), once the FRB redshifts are known …

This book focus on examining the thermodynamic properties of various prominent field
theories concerning high-energy and condensed matter physics. We make the usage of the …
