Modified dispersion relations and a potential explanation of the EDGES anomaly
European Physical Journal C: Particles and Fields, 2022 The Experiment to Detect the Global Epoch of Reionisation Signature (EDGES) collaboration has recently reported an important result related to the absorption signal in the Cosmic Microwave Background radiation spectrum. This signal corresponds to the red-

New Journal of Physics, 2021 In this article, we present a unified reciprocal quantum electrodynamics (QED) formulation of free-electron and quantum–light interaction. For electron–light interactions, we bridge the underlying theories of photon-induced near-field electron microscopy,

Chern-Weil global symmetries and how quantum gravity avoids them
Journal of High Energy Physics, 2021 We draw attention to a class of generalized global symmetries, which we call “Chern-Weil global symmetries,” that arise ubiquitously in gauge theories. The Noether currents of these Chern-Weil global symmetries are given by wedge products of gauge field ...

Quantum measurement in a family of hidden-variable theories [PDF]
, 1996 The measurement process for hidden-configuration formulations of quantum mechanics is analysed. It is shown how a satisfactory description of quantum measurement can be given in this framework.

Universally finite gravitational and gauge theories
Nuclear Physics B, 2015 It is well known that standard gauge theories are renormalizable in D=4 while Einstein gravity is renormalizable in D=2. This is where the research in the field of two derivatives theories is currently standing.

Gravitational Corrections to Fermion Masses in Grand Unified Theories [PDF]
, 2011 We reconsider quantum gravitational threshold effects to the unification of fermion masses in Grand Unified Theories. We show that the running of the Planck mass can have a sizable effect on these thresholds which are thus much more important than ...

I-Theory: A Unifying Quantum Theory?
Journal of High Energy Physics, Gravitation and Cosmology, 2019 This paper gives an overview of a new theory called the “I-Theory”, in the context of several accepted theories in physics and cosmology. This paper reviews the salient features of the “I-Theory”, which introduces new particles like I, S∞ and A1 particles and provides a fuller understanding about Dark Matter, Dark Energy, Matter/Anti Matter and the ...

Reduction of parameters in Finite Unified Theories and the MSSM
Nuclear Physics B, 2018 The method of reduction of couplings developed by W. Zimmermann, combined with supersymmetry, can lead to realistic quantum field theories, where the gauge and Yukawa sectors are related.

Dynamical Reduction Models: present status and future developments [PDF]
, 2007 We review the major achievements of the dynamical reduction program, showing why and how it provides a unified, consistent description of physical phenomena, from the microscopic quantum domain to the macroscopic classical one.

Interacting diffusive unified dark energy and dark matter from scalar fields
European Physical Journal C: Particles and Fields, 2017 Here we generalize ideas of unified dark matter–dark energy in the context of two measure theories and of dynamical space time theories. In two measure theories one uses metric independent volume elements and this allows one to construct unified dark ...
