Topological Spin‐Texture Transitions in van der Waals Magnets Revealed by X‐Ray Fourier Transform Holography

Advanced Materials, EarlyView.
Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Underlining some aspects of twin paradox in a high school lesson [PDF]

Revista Brasileira de Ensino de Física
In this paper we want to describe one of our lessons held within the educational project “Liceo Matematico” of the Salerno University. We have analyzed the so-called and well-known “Twin Paradox”.

Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators

Advanced Materials, EarlyView.
A bulk scintillating nanocomposite is engineered from CsPbBr3 nanoplatelets and Ag nanocubes to support exciton–plasmon strong coupling under X‐ray excitation. The resulting hybrid polaritonic states appear directly in radioluminescence, opening a route toward polariton‐enabled scintillator design beyond conventional Purcell enhancement.

Modified Lorentz transformations in deformed special relativity

, 2017
We have extended a recent approach to Deformed Special Relativity based on deformed dispersion laws, entailing modified Lorentz transformations and, at the same time, noncommutative geometry and intrinsically discrete spacetime.

The Simplest Form of the Lorentz Transformations [PDF]

, 2023
We report the simplest possible form to compute rotations around arbitrary axis and boosts in arbitrary directions for 4-vectors (space-time points, energy-momentum) and bi-vectors (electric and magnetic field vectors) by symplectic similarity ...

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

Matrix Representation of Planar Lorentz Transformations in Extended (2 + 2)-Dimensional Spacetime

Advances in Mathematical Physics
A matrix formulation of Lorentz transformations restricted to planar motion is developed within an extended 2+2-dimensional spacetime framework. Focusing on inertial frames in relative motion confined to the XY-plane, the analysis begins with radial ...

Extended Linear and Nonlinear Lorentz Transformations and Superluminality

Advances in High Energy Physics, 2013
Two broad scenarios for extended linear Lorentz transformations (ELTs) are modeled in Section 2 for mixing subluminal and superluminal sectors resulting in standard or deformed energy-momentum dispersions.
