Derivation of the Relativistic Doppler Effect from the [PDF]

, 2008
This paper demonstrates that calculation and interpretation of the relativistic Doppler effect is possible using only the Lorentz force and relativity theory. This method eliminates the need for the Lorentz transformation and time dilation.

Bursting detection by Variable-Interval Time-Averaging (VITA) on spanwise oscillated turbulent channel flow

MATEC Web of Conferences, 2016
The main aim of the study is to detect the bursting phenomenon in spanwise oscillated Lorentz force applied turbulent channel flow. Regarding the biggest reason of the turbulence production is known as the bursting phenomenon, detecting the decrease on ...

Giant Anisotropy and High Second‐Order Nonlinearity of 3R‐MoS2 for Multifunctional Photonics

Advanced Materials, EarlyView.
Graphical abstract highlights, 3R‐polytype of MoS2 (3R‐MoS2) as a multifunctional photonic platform enabled by giant optical anisotropy and optical nonlinearities, demonstrating subdiffractional waveguiding, giant second‐harmonic (SH) generation, and high‐performance reflective polarization control.

Impact of magnetostriction mechanism on frequency manipulation ultrasonic steering in electromagnetic acoustic transducers

Electronics Letters
In this paper, the impact of the magnetostriction mechanism is considered as the focus. An axisymmetric FEM model of the spiral‐coil electromagnetic acoustic transducers (EMAT) is established to conduct the simulation.

Field-theoretic derivation of bubble-wall force

Journal of High Energy Physics, 2021
We derive a general quantum field theoretic formula for the force acting on expanding bubbles of a first order phase transition in the early Universe setting.

Uniaxial Stress Enhanced Anisotropic Magnetoresistance and Superconductivity in the Kagome Superconductor LaRu3Si2

Advanced Materials, EarlyView.
We identify strong anisotropy in the upper critical field and magnetoresistance in the kagome superconductor LaRu3Si2, revealing pronounced electronic anisotropy. Uniaxial stress enhances magnetoresistance and Tc, with a positive correlation suggesting an electronic pairing mechanism.

Problems of Lorentz Force and Its Solution [PDF]

, 2020
In the article is proven that the Lorentz force is the consequence of the dependence of the scalar potential of charge on the speed. It is shown that the dependence of Lorentz force on the speed is nonlinear, as previously supposed.

The Avez-Seifert theorem for the relativistic Lorentz force equation [PDF]

, 2004
In this paper we prove an extension of the Avez-Seifert theorem to the relativistic Lorentz force equation. Let (M,g) be a globally hyperbolic space-time, F an exact 2-form on M representing the electromagnetic field, (F) over cap the Lorentz force ...

Changes in Photospheric Lorentz Force in Eruptive and Confined Solar Flares

The Astrophysical Journal
Solar flares are known to leave imprints on the magnetic field in the photosphere, often manifested as an abrupt and permanent change in the downward-directed Lorentz force in localized areas inside the active region.

The Lorentz force and superconductivity [PDF]

Physics Letters A, 2003
To change the velocity of an electron requires that a Lorentz force acts on it, through an electric or a magnetic field. We point out that within the conventional understanding of superconductivity electrons appear to change their velocity in the absence of Lorentz forces.
