Dressed vs. pairwise states, and the geometric phase of monopoles and charges

Journal of High Energy Physics, 2023
We construct the Faddeev-Kulish dressed multiparticle states of electrically and magnetically charged particles, incorporating the effects of real and virtual soft photons. We calculate the properties of such dressed states under Lorentz transformations,

Solvent‐Free Fabrication Methods of Metal Halide Perovskites

Advanced Materials, EarlyView.
This review explores the current status of solvent‐free fabrication methods of metal halide perovskites, such as thermal evaporation, magnetron sputtering, pulsed laser deposition, e‐beam and atomic layer deposition, solid phase growth, and laser printing.

Why do spacecraft always experience a black-out area that disrupts communications when they return to Earth?

ScienceOpen Research
In this paper, Lorentz factor and Lorentz transformations are modified based on the new aether theory, and the blackout which leads to communication interruption of high-speed moving objects is analyzed by using the modified Lorentz electromagnetic field

Field-dependent quantum gauge transformation

, 2014
In this paper we generalize the quantum gauge transformation of Maxwell theory obtained through gaugeon formalism. The generalization is made by making the bosonic transformation parameter field-dependent.

Lorentz Transformations

, 2011
This paper describes a particularly didactic and transparent derivation of basic properties of the Lorentz group. The generators for rotations and boosts along an arbitrary direction, as well as their commutation relations, are written as functions of the unit vectors that define the axis of rotation or the direction of the boost (an approach that can ...

Accompanying Structural Transformations in Polarity Switching of Heavily Doped Conjugated Polymers

Advanced Materials, EarlyView.
The polarity switching of heavily doped p‐type conjugated polymers (CPs) toward environmentally stable electron‐rich thin films is demonstrated. Multiscale analyses, incorporating spectroscopic, electrochemical, and scattering techniques, reveal structural and chemical transformations induced by excessive doping with AuCl3.

Relativity in cosmologically preferred frame and the UHECR paradox

Bibechana, 2014
The Greisen-Zatsepin-Kuzmin (GZK) cutoff (5 × 1019eV) of special relativity in the observed ultra high energy cosmic rays (UHECR) spectrum is one of the most puzzling paradoxes in physics.

The covariance of chiral fermions theory

Journal of High Energy Physics, 2019
The quasiclassical theory of massless chiral fermions is considered. The effective action is derived using time-dependent variational principle which provides a clear interpretation of relevant canonical variables.
