Helical Electron Beam Micro‐Bunching by High‐Order Modes in a Micro‐Plasma Waveguide
ABSTRACT Electron acceleration by a high‐power Laguerre‐Gaussian pulse in a micro‐plasma waveguide is investigated. When the incident laser travels in the waveguide, electrons on the wall are extracted into the vacuum core and accelerated by the longitudinal field of the waveguide mode.

Regularization of f(T) Gravity Theories and Local Lorentz Transformation
We regularized the field equations of f(T) gravity theories such that the effect of local Lorentz transformation (LLT), in the case of spherical symmetry, is removed.

Lorentz transformation from an elementary point of view
Elementary methods are used to examine some nontrivial mathematical issues underpinning the Lorentz transformation. Its eigen-system is characterized through the exponential of a $G$-skew symmetric matrix, underlining its unconnectedness at one of its ...

Designed and demonstrated a flexible metamaterial absorber via loss engineering for large‐area ultra‐broadband infrared extinction, providing a new method for miniaturization of absorbers and flexible optical devices. ABSTRACT The advancement of compact and wearable optical systems is critically limited by the lack of high‐performance, integrable ...

Calculation of the same Lorentz factor using the opposite approach
This article extends the law of electromagnetic oscillation to form a theoretical system of spatial particles. According to this theory, the speed of light is variable and motion is absolute.

Wigner–Souriau translations and Lorentz symmetry of chiral fermions
Chiral fermions can be embedded into Souriau's massless spinning particle model by “enslaving” the spin, viewed as a gauge constraint. The latter is not invariant under Lorentz boosts; spin enslavement can be restored, however, by a Wigner–Souriau (WS ...

ZnSb reduces carrier concentration and suppresses Te volatilization, while Se substitution within QLs softens phonons and enhances anharmonicity. Swapped bilayers near twin boundaries strengthen phonon scattering and interlayer bonding. As a result, the optimal sample achieves an ultra‐high zT ∼1.51, cooling temperature difference of ∼70 K, power ...
