Quantum Entanglement of Moving Bodies

, 2002
We study the properties of quantum information and quantum entanglement in moving frames. We show that the entanglement between the spins and the momenta of two particles can be interchanged under a Lorentz transformation, so that a pair of particles ...

Spin‐Polarized Antiferromagnets for Spintronics

Advanced Materials, EarlyView.
This review highlights recent advances in anomalous and spin transport phenomena in spin‐polarized antiferromagnets. Key effects—including the anomalous Hall, Nernst, and magneto‐optical effects—are discussed across various antiferromagnetic platforms.

A new perspective on spacetime 4D rotations and the SO(4) transformation group

Results in Physics, 2019
In quantum field theory, every conservation law is enforced by adequate symmetries. The Lorentz group, which represents two continuous symmetries: rotations in 3D Euclidean space and Lorentz boosts, generates conservation of the angular momentum tensor ...

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

Covariant Response Theory and the Boost Transform of the Dielectric Tensor

, 2017
After a short critique of the Minkowski formulae for the electromagnetic constitutive laws in moving media, we argue that in actual fact the problem of Lorentz-covariant electromagnetic response theory is automatically solved within the framework of ...

Stimuli‐Responsive Low‐Frequency Terahertz Absorption ON‐OFF Switchability in Spin‐Crossover Material

Advanced Materials, EarlyView.
A switchable Fe(II)–Hg(II) coordination polymer exhibits reversible ON‐OFF terahertz (THz) absorption through temperature‐ and light‐induced spin‐crossover. The material shows strong, tunable THz responses linked to phonon modes around Fe(II) centers, supported by spectroscopic measurements and calculations.

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.

Beta‐Lactoglobulin for Water‐Based and Tunable Nanostructure Templating of Printed Titania Thin Films: The Influence of pH Value and Protein Concentration

Advanced Materials Interfaces, EarlyView.
The synthesis route for the fabrication of nanostructured titania thin films focuses on water‐based solutions, abundant, nontoxic materials, and a highly scalable deposition technique. Using beta‐lactoglobulin enables tunable titania thin film templating and allows for different domain sizes, porosities, and morphologies.

Comment on ‘Quantum principle of relativity’

New Journal of Physics, 2022
Recently Dragan and Ekert (2020 New. J. Phys . 22 033038) presented arguments that probabilistic dynamics inherent in the realm of quantum physics is related to the propagation of superluminal particles.

On The Theory of Time dilation in Chemical Kinetics

, 2017
The rates of chemical reactions are not absolute but their magnitude depends upon the relative speeds of the moving observers. This has been proved by unifying theories of chemical kinetics, which are transition state theory, collision theory, RRKM and ...
