, 2014 The ability of the Lorentz force to link a mechanical displacement to an electrical current presents a strong interest for medical acoustics, and three applications were studied in this thesis. In the first part of this work, a hydrophone was developed for mapping the particle velocity of an acoustic field.

Helical Electron Beam Micro‐Bunching by High‐Order Modes in a Micro‐Plasma Waveguide
Advanced Science, EarlyView.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.

Derivation of the Relativistic Doppler Effect from the
, 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.

Chaos and maps in relativistic rynamical systems
Discrete Dynamics in Nature and Society, 2000 The basic work of Zaslavskii et al showed that the classical non-relativistic electromagnetically kicked oscillator can be cast into the form of an iterative map on the phase space; the resulting evolution contains a stochastic flow to unbounded energy ...

Rectified Lorentz Force from Thermal Current Fluctuations
PhysicsIn a conducting medium held at finite temperature, free carriers perform Brownian motion and generate fluctuating electromagnetic fields. In this paper, an averaged Lorentz force density is computed that turns out to be nonzero in a thin subsurface layer,

Advanced Science, EarlyView.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 ...

The Avez-Seifert theorem for the relativistic Lorentz force equation
, 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 ...

Advanced Science, EarlyView.The weakly‐solvating TFMSPyr electrolyte tailors the Li+ solvation structure by suppressing solvent coordination and promoting anion‐dominated solvation. This unique solvation environment induces preferential anion decomposition at electrode interfaces, forming robust inorganic rich S/CEI.
